FITS Header keywords

The science frames of the Levy spectrometer contain a number of FITS header values. There are two sources for these keywords, one is the APF UCAM controller. The second are a list of APF KTL service keywords.

KTL keywords in the FITS header

Below we have a list of KTL keywords with the corresponding FITS header keyword. The comment lists the units, if any, and a short description. In addition, the command gshow -s service.keyword -lh will provide the long help description of the keyword on any of the four linux hosts for the APF.
