  Data Set Overview

   For the TV SYSTEM, 95 images were sent as a 7-d FITS file with
little information in the FITS headers.  In addition, to the size of
the image (NAXIS1 and NAXIS2), the values for NAXIS3 and NAXIS4 were
labeled 'TIME'; the first was interpreted as exposure time in seconds.
The following procedure was used to convert NAXIS3 information:
                                                                              
- The IKI datasets header have a field called CRVAL3 which appears to         
  contain a count of seconds since midnight.                                  
                                                                              
- We converted the CRVAL3 value to a day fraction and matched patterns of
  exposure times between this dataset and similar TVS data from KFKI.         
                                                                              
- the IKI time is greater than the KFKI time for the corresponding            
  dataset by about 0.00646 days (approximately 9.3 minutes).
(We interpret the latter as the light correction time but choose not
to make the correction but leave the IKI data as submitted."
