middle_from_wcs

jwst.extract_1d.source_location.middle_from_wcs(wcs, bounding_box, dispaxis)[source]

Calculate the effective middle of the spectral region.

Parameters:
wcsWCS

WCS for the input data model, containing detector to wavelength transforms.

bounding_boxtuple

A pair of tuples, each consisting of two numbers. Represents the range of useful pixel values in both dimensions, ((xmin, xmax), (ymin, ymax)).

dispaxisint

Dispersion axis.

Returns:
middle_dispfloat

Middle pixel in the dispersion axis.

middle_xdispfloat

Middle pixel in the cross-dispersion axis.

middle_wavelengthfloat

Wavelength at the middle pixel.
