fore_optics_flat
- jwst.flatfield.flat_field.fore_optics_flat(wl, f_flat_model, exposure_type, dispaxis, slit_name, slit_nt)[source]
Extract the flat for the fore optics part.
- Parameters:
- wlndarray
Wavelength at each pixel of the 2-D slit array.
- f_flat_model
NirspecFlatModel,NirspecQuadFlatModel, or None Flat field for the fore optics.
- exposure_typestr
The exposure type refers to fixed_slit, IFU, or MSA.
- dispaxisint
1 means horizontal dispersion, 2 means vertical dispersion.
- slit_namestr or None
The name of the slit currently being processed.
- slit_ntnamedtuple or None
For MOS data (only), this is used to get the quadrant number and the indices of the current shutter in the Y and X directions.
- Returns:
- f_flatndarray of float32
The computed flat field for the fore optics.
- f_flat_dqndarray of uint32
The associated data quality array.
- f_flat_errndarray of float32 or None
The associated error array.
