chopnod_properties¶
- sofia_redux.instruments.forcast.chopnod_properties.chopnod_properties(header, update_header=False)[source]¶
Returns the chop nod properties in the detector reference frame
Finds the chop and nod amplitudes in the detector frame. It also returns if the chop/nod configuration was NMC.
- Parameters:
- headerastropy.io.fits.header.Header
- update_headerbool, optional
Update the header with plate scale (in HISTORY)
- Returns:
- dict
chop: dict nod: dict nmc: bool c2nc2 : int
Notes
This function is only useful in the case of C2 or C2N observations
Assume SOFIA plate scale = 0.768 arcsec/pixel
