get_tess_pixel_xy

tessilator.tessilator.get_tess_pixel_xy(t_targets)

Get the pixel x-y positions for all targets in a Sector/Camera/CCD mode.

For a given pair of celestial sky coordinates, this function returns table rows containing the sector, camera, CCD, and x/y position of the full-frame image fits file, so that all stars located in a given (large) fits file can be processed simultaneously. After the table is returned, the input table is joined to the input table on the source_id, to ensure this function only needs to be called once.

This function is only used if the tessilator program runs over the calibrated full-frame images - i.e., when the “all_cc” function is called.

Parameters:

t_targetsastropy.table.Table

The input table created by the function get_gaia_data.py.

Returns:

xy_tableastropy.table.Table

Output table containing the (x, y) pixel positions for each target.
