Methods Documentation

classmethod from_tvac_raw(model)

Convert TVAC/FPS into ScienceRawModel

romancal supports processing a selection of files which use an outdated schema. It supports these with a bespoke method that converts the files to the new format when they are read in dq_init. This conversion does not do a detailed mapping between all of the new and old metadata, but instead opportunistically looks for fields with common names and assigns them. Other metadata with non-matching names is simply copied in place. This allows processing to proceed and preserves the original metadata, but the resulting files have duplicates of many entries.

Parameters:

model (ScienceRawModel, TvacModel, FpsModel) – Model to convert from.

Returns:

science_raw_model – The ScienceRawModel built from the input model. If the input was a ScienceRawModel, that model is simply returned.

Return type:

ScienceRawModel
