Maintaining SOFIA Redux

The Stratospheric Observatory for Infrared Astronomy (SOFIA) has gathered a considerable amount of scientific databetween first light in May 2010 to the final observing flight in September 2022. The joint mission by NASA and DLR produceda diverse set of astronomical data from several science instruments. While the mission was still active, the SOFIA Data Processing Software Team worked in cooperation with experts from thescience instrument teams in order to write and maintain the reduction software suite "SOFIA Redux". The framework writtenin Python provides general purpose data reduction functions and dedicated modules for the SOFIA instruments EXES,FIFI-LS, FLITECAM, FORCAST, and HAWC+. It was continually improved and maintained until the end of the mission, with amost recent release of patch updates in August 2023. The SOFIA Data Center has forked the open source code base fromGitHub and continues to keep the code fresh, accommodating API changes for underlying Python libraries. Furthermore, newfeatures and improved reduction techniques are being implemented into the instrument reduction pipelines (see SDC FIFI-LSposter from A. Bryant)
