jwst.wfss_contam.disperse.disperse(xs, ys, fluxes, source_ids_per_pixel, order, wmin, wmax, sens_waves, sens_resp, direct_image_wcs, grism_wcs, naxis, oversample_factor=2)

Compute the dispersed image pixel values from the direct image.

Parameters:

xsndarray

Flat array of X coordinates of pixels in the direct image

ysndarray

Flat array of Y coordinates of pixels in the direct image

fluxesndarray

Fluxes of the pixels in the direct image corresponding to xs, ys. These should have units of MJy/sr.

source_ids_per_pixelint array

Source IDs of the input pixels in the segmentation map

orderint

Spectral order number

wminfloat

Minimum wavelength for dispersed spectra

wmaxfloat

Maximum wavelength for dispersed spectra

sens_wavesfloat array

Wavelength array from photom reference file. Expected unit is micron.

sens_respfloat array

Response (flux calibration) array from photom reference file. Expected units are (micron) * (MJy / sr) / (ADU/s).

direct_image_wcsWCS object

WCS object for the direct image and segmentation map

grism_wcsWCS object

WCS object for the grism image

naxistuple

Dimensions of the grism image (naxis[0], naxis[1])

oversample_factorint, optional

Factor by which to oversample the wavelength grid

Returns:

outputs_by_sourcedict

Dictionary containing dispersed images and bounds for each source ID in the specified spectral order.
