getcalpath

sofia_redux.instruments.forcast.getcalpath.getcalpath(header, pathcal=None)

Return the path of the ancillary files used for the pipeline.

Looks up default calibration files and other reference data in the calibration data path, based on the characteristics of the observation, as recorded in the input header.

Parameters:

headerastropy.io.fits.header.Header

pathcalstr, optional

File path to calibration data directory that contains the default calibration files. If not provided, the default data location will be used (sofia_redux.instruments.forcast/data).

Returns:

collections.OrderedDict
