Generating the FIRE Structure
Firehose stores all information about which flat, arc, and telluric files are paired with which science frames in an IDL structure for portability. The next step of the reduction process is to generate this structure, and then edit it to ensure it reflects the pairings you want (e.g. eliminating saturated tellurics, etc.). This procedure is done by a largely automated, and fairly complicated procedure. It performs the following procedures without user intervention:
