class jwst.datamodels.MiriLRSSpecwcsModel(init=None, wavetable=None, x_ref=None, y_ref=None, x_ref_slitless=None, y_ref_slitless=None, v2_vert1=None, v2_vert2=None, v2_vert3=None, v2_vert4=None, v3_vert1=None, v3_vert2=None, v3_vert3=None, v3_vert4=None, **kwargs)

Bases: ReferenceFileModel

A model for a reference file of type “specwcs” for MIRI LRS Slit.

The model is for the specwcs for LRS Fixed Slit and LRS Slitless data.

Initialize the model.

Parameters:

initstr, None, optional

File name for input file in ASDF format from which to initialize the model.

wavetablenumpy 2-D array

For each row in the slit hold wavelength, and x center, ycenter, x and y box region corresponding to the wavelength

x_reffloat

X-coordinate of reference position of fixed slit aperture

y_reffloat

Y-coordinate of reference position of fixed slit aperture

x_ref_slitlessfloat

X-coordinate of reference position of slitless aperture

y_ref_slitlessfloat

Y-coordinate of reference position of slitless aperture

v2_vert1float

Slit vertex 1 in V2 frame

v2_vert2float

Slit vertex 2 in V2 frame

v2_vert3float

Slit vertex 3 in V2 frame

v2_vert4float

Slit vertex 4 in V2 frames

v3_vert1float

Slit vertex 1 in V3 frames

v3_vert2float

Slit vertex 2 in V3 frames

v3_vert3float

Slit vertex 3 in V3 frames

v3_vert4float

Slit vertex 4 in V3 frames

**kwargs

Additional keyword arguments to pass to ReferenceFileModel.

Attributes Summary

reftype
schema_url	The schema URI to validate the model against.

Methods Summary

populate_meta()
validate()	Check that required reference file keywords are set.

Attributes Documentation

reftype = 'specwcs'

schema_url = 'http://stsci.edu/schemas/jwst_datamodel/specwcs_miri_lrs.schema'

The schema URI to validate the model against. If None, only basic validation of required metadata properties (filename, model_type) will occur.

Methods Documentation

populate_meta()

validate()

Check that required reference file keywords are set.
