get_seg_iso_flux

grizli.prep.get_seg_iso_flux(data, seg, tab, err=None, fill=None, verbose=0)

Integrate flux within the segmentation regions.

Parameters

data2D array

Image data

seg2D array

Segmentation image defining the ISO contours

tabTable

Detection catalog with columns (at least) number / id, xmin, xmax, ymin, ymax. The id column matches the values in seg.

err2D array

Optional uncertainty array

fillNone, array

If specified, create an image where the image segments are filled with scalar values for a given object rather than computing the ISO fluxes

verbosebool/int

Status messages

Returns

iso_fluxarray

Summed image flux within the contours defined by the seg map

iso_errarray

Uncertainty if err specified

iso_areaarray

Area of the segments, in pixels

filled_data2D array

If fill specified, return an image with values filled within the segments, e.g., for a binned image
