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.
