sofia_redux.instruments.flitecam: FLITECAM Data Reduction Algorithms#

The sofia_redux.instruments.flitecam package contains data reduction algorithms for the FLITECAM instrument. It is designed to be used with the sofia_redux package, so it does not provide its own interfaces or workflows. See the sofia_redux.pipeline documentation for more information on the pipeline interfaces, or the API documentation below for more information on FLITECAM algorithms.
