get_uv_points_data

stixpy.calibration.visibility.get_uv_points_data(d_det: Quantity, Unit("mm")]=<Quantity 47.78 mm>, d_sep: Quantity, Unit("mm")]=<Quantity 545.3 mm>)

Return the STIX (u,v) points coordinates defined in [1], ordered with respect to the detector index.

It will return the precalculated cached data if the default values for d_det and d_sep are used.

Parameters:

• d_det (u.Quantity[u.mm] optional) – Distance between the rear grid and the detector plane (in mm). Default, 47.78 * u.mm

• d_sep (u.Quantity[u.mm] optional) – Distance between the front and the rear grid (in mm). Default, 545.30 * u.mm

Returns:

A dictionary containing sub-collimator indices, sub-collimator labels and coordinates of the STIX (u,v) points (defined in arcsec ^-1)
