grizli.jwst_utils.mast_exposure_attitude(filename='jw06640052001_0310h_00001_nrs1_rate.fits', row=None, gs_pa_offset=-0.1124, verbose=True, **kwargs)[source]¶

Generate JWST spacecraft attitude matrix relevant for a particular exposure from MAST query columns

Parameters

filenamestr: JWST exposure filename
gs_pa_offsetfloat: Empirical offset added to gs_v3_pa from the MAST query to match ROLL_REF in the science headers, since ROLL_REF doesn’t seem to be available directly from queries to the MAST db. The default value was derived from an MSA exposure.

Returns

att(3, 3) array-like: Attitude matrix for use with pysiaf
