get_coefficients¶
- sofia_redux.instruments.forcast.imgnonlin.get_coefficients(header, camcap, update=False)[source]¶
Get non-linearity coefficients from the header based on camera and capacitance
- Parameters:
- headerastropy.io.fits.header.Header
- camcapstr
camera + 2-letter-capacitance, e.g., SWCHI, LWCLO, etc.
- updatebool, optional
If True, update the header with the coefficients. keys will be NLINC# where # represents a number. The NLC + camap key will also be removed as it does not fit in the line. A HISTORY message will also be appended stating the read coefficients
- Returns:
- numpy.ndarray
float coefficient values from header
