DATA_SET_DESCRIPTION |
Data Set Overview: For the TV SYSTEM, 39 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 0.00574 days (approximately 8.3 minutes). (We interpret the latter as the light correction time but choose not to make the correction but leave the IKI data as submitted.
