scopesim.optics.image_plane_utils.calc_table_footprint(table: Table, x_name: str, y_name: str, tbl_unit: str, new_unit: str, padding=None) → ndarray#

Equivalent to calc_footprint(), but for tables instead of images.

Parameters:

  • table (astropy.table.Table) – Table containing data.

  • x_name (str) – Name of the column in table to use as x-coordinates.

  • y_name (str) – Name of the column in table to use as y-coordinates.

  • tbl_unit (str) – Default unit to use for x and y if no units are found in table.

  • new_unit (str) – Unit to convert x and y to, can be identical to tbl_unit.

  • padding (astropy.units.Quantity, optional) – Constant value to subtract from minima and add to maxima. If used, must be Quantity with same physical type as x and y. If None (default), no padding is added.

Returns:

extent – Array containing corner points (clockwise from bottom left). Format and order are equivalent to the output of astropy.wcs.WCS.calc_footprint().

Return type:

(4, 2) array
