                                 A Listing of Errors in the Large-Scale Phenomena (L-SP)                                          
                                             Portion of the IHW Archive                                                           
                                                                                                                                  
                                                                                                                                  
Despite the best efforts made to create a perfect L-SP Discipline contribution to the IHW Archive, a small level of (mostly minor)
errors has been detected during the final assembly of data, headers, tables, and indices.  The purpose of this document is to     
enumerate the errors, specify where in the archive they are located, and indicate the correct values.  There are no known errors  
in the L-SP data themselves, i.e., in the 2-D image arrays; rather, the occasional errors are in the metadata (the "data about the
data").  Metadata exist in a number of forms for the L-SP Discipline, most importantly: individual FITS headers, the NETLARGE.IDX 
index, and the LS_PHEN.IDX index.  [The latter index is colloquially referred to as the L-SP "Printed Archive index", because in  
its content and structure it is virtually identical to the L-SP contribution to the planned IHW Printed Archive]                  
                                                                                                                                  
The L-SP portion of the IHW digital Archive is rather different from that of the other Disciplines in that the primary repository 
of data is a series of 18 discs dedicated to compressed L-SP imagery (Volumes 1-18).  Even in compressed form, the 2-D image      
arrays are quite large (typically 8 Mb per file), a situation which demanded a location separate from that of the other           
Disciplines (characterized by much smaller files).  The compressed image discs contain not only the large image arrays for the    
L-SP Discipline, but also smaller versions of the images for browsing purposes (the so-called "browse images"), and a full        
assortment of indices and documents, including the NETLARGE.IDX index, which contains nearly every FITS keyword for all 3383 L-SP 
images.  Nonetheless, the so-called "mixed discs" (Volumes 19-23, containing the multi-discipline IHW data) do contain the L-SP   
browse images, deposited on CD-ROM a second time in order to facilitate inter-Discipline comparisons, as well as the NETLARGE.IDX 
and LS_PHEN.IDX indices.  The following small table shows at a glance where some of the various L-SP data/metadata products reside
on CD-ROM.

A significant amount of time elapsed between the premastering of the L-SP compressed image discs and the mixed discs, which has   
permitted the correction of some L-SP errors in time for the latter set of discs.  This goes beyond the mere mention of errors in 
this "errata file":  specifically, 75 browse image headers were revised for their deposit on the mixed discs, and because the     
NETLARGE.IDX index is created from FITS headers, the mixed-disc version of it is correspondingly more correct than its predecessor
on the compressed discs.  In the table below the (known) errors are indicated, along with the locations where the errors occur. In
some cases, errors beyond the 75 edited headers discussed above were discovered after the mixed disc premastering was well        
underway, and in these cases the errors were propagated into the mixed discs.  It is regrettable that these could not be          
corrected, but in any case their existence is indicated here for the benefit of the IHW Archive user.                             
                                                                                                                                  
The "Printed Archive index" (LS_PHEN.IDX) benefitted, in a sense, by being the last major repository of L-SP metadata to be edited
and premastered.  However, the IHW Archive user should be forewarned that there are many differences between the parameter values 
in the Printed Archive index and the keywords contained in FITS headers and NETLARGE.IDX.  The reason is that due to field-width  
limitations, the Printed Archive entries often had to be "edited-down" (e.g., "Technical Pan 2415" became "TP2415" in the Emulsion
column).  The user is, therefore, warned against using Printed Archive values as "search strings" in the NETLARGE.IDX index (for  
example).                                                                                                                         
                                                                                                                                  
A summary word is perhaps in order.  Every effort was made to make the L-SP contribution to the IHW archive as error-free as      
possible.  Realistically, however, a task this large cannot be carried out in the complete absence of mistakes.  One can only hope
that the errors are relatively few in number, and in any case are not very serious.  It is my hope that the table below may be    
seen to satisfy both criteria.

I.  GENERAL (SYSTEMATIC) ERRORS                                                                                                   
                                                                                                                                  
The observatory longitude for all images obtained at the Tahiti station of the L-SP Discipline's so-called "Island Network" is    
incorrectly given in the FITS headers as LONG-OBS = 149/34/00 deg/min/arcsec.  The correct value is 210/26/00 (360 degrees minus  
original value).  The SYSTEM Code for these observations is 35006101; all the images are provided as "dataless headers."          
                                                                                                                                  
K. Sivaraman was listed as the OBSERVER for all L-SP imagery taken at the Indian Institute of Astrophysics/Kavalur Station (SYSTEM
Code 35000503), and at the [same Institute's] Kodaikanal Station (SYSTEM Code 35000504).  In fact, Dr. Sivaraman was the submitter
of these plates to the L-SP Discipline, not the sole observer.  The platelogs from these facilities did not record observers, and 
we apologize to those whose efforts at the corresponding telescopes were not recognized.                                          
                                                                                                                                  
                                                                                                                                  
II.  SPECIFIC ERRORS                                                                                                              
                                                                                                                                  
The following table details the nature of these errors, as well as providing correct values for the problematic keyword(s).  The

NOTE 1:  Ironically, some eleven headers are correct in the Observer keyword on the compressed discs, and are actually incorrect  
on the mixed set.  The reason for this is that those compressed-disc headers were manually-corrected on the CD-ROM "premastering  
workstation", and we forgot to incorporate the changes in the archived set of 3383 headers (which would be used later in the      
construction of the mixed discs).                                                                                                 
                                                                                                                                  
NOTE 2:  for LSPN1087-1103 inclusive, the EXPOSURE keyword value was numerically correct, but was shifted right one column in the 
compressed-disc headers, causing problems in the construction of the NETLARGE.IDX index on those discs.                           
                                                                                                                                  
NOTE 3:  The apostrophe in O'Brien's name resulted in a truncation in the OBSERVER field in NETLARGE.IDX(C).  The mixed-disc      
headers have not been edited to remove the apostrophe, and the NETLARGE.IDX(M) has therefore been hand-edited.                    
                                                                                                                                  
NOTE 4:  In the compressed-disc headers for LSPN2109-2145 [non-inclusive] above, the LONG-OBS keyword was numerically correct,    
but was shifted right one column, causing an error in that keyword in the NETLARGE.IDX(C) index.                                  
                                                                                                                                  
NOTE 5:  Apostrophe was removed in mixed-disc headers for the benefit of proper keyword extraction using FITS readers.            
                                                                                                                                  
NOTE 6:  These observer errors are for SYSTEM=30330100 calibration files.  The associated Halley data files are correct.
