Source code: SPICE_DATA::get_window_position

Class: SPICE_DATA

Description

This function returns the position of the window on the CCD, starting with 0 if idl_coord is set, 1 otherwise. The position is given as a 4-element vector, with [lambda0, lambda1, y0, y1]. Note: y0 > y1, but lambda0 < lambda1.

Syntax

array = spice_object->get_window_position( window [, detector=detector] [, /idl_coord] [, /reverse_y] [, /reverse_x] [, /no_warning] )

Return Value

Integer array with 4 elements [lambda0, lambda1, y0, y1].

Arguments

window

The index or name of the window.

Keywords

idl_coord

If set, the coordinates start with zero, instead of with 1.

reverse_y

If set, y-coordinates are given as (CCD-size +1 - (original y-coords)).

reverse_x

For dumbbells x-coordinates are flipped. If this keyword is set, the coordinates will be flipped again, i.e. values of PXBEG3 and PXEND3 will be swapped.

no_warning

If set, warnings about x-flipping will be suppressed.

Optional Output

detector

Set this keyword to a named variable, which then will be set to either 1 or 2 to indicate on which detector the window is.
