BULLETIN: kastfocus program An IDL program called kastfocus has been written to assist focusing the KAST spectrograph. This is an interactive program allowing observers to select lines from an arc lamp spectrum and calculate the median FWHM across the spectrum. The median FWHM for images taken at different collimator focus positions is also plotted and a best collimator focus position is calculated. ACTIONS: Kastfocus runs under IDL on orthrus. For more information on using this simple program see the on-line KAST manual kastfocus page. POSTED: 02/04/02 Elinor Gates (egates@ucolick.org) |
