Source code: SPICE_DATA::get_instr_y_vector

Class: SPICE_DATA

Description

Returns a vector containing the coordinates (instrument y-direction) for each pixel in the second dimension, either the actual size of the selected window or the full CCD size.

Syntax

instr_y_coords = spice_object->get_instr_y_vector( window [, x=x] [, lambda=lambda] [, time=time] [, /diff_rot] [, /full_ccd] )

Return Value

Float array, coordinates in arcsec.

Arguments

window

The index or name of the window.

OPTIONAL INPUTS:

x

The index of the x-coordinate of the pixel, default is the middle of the window

lambda

The index of the wavelength coordinate of the pixel, default is the middle of the window

time

The index of the time coordinate of the pixel, default is the middle of the window

Keywords

diff_rot

If set, applies the differential rotation correction to the x- and y-coordinates using spice_diff_rot_coord. If this keyword is set, then x, lambda and time provided must be within the actual data volume.

full_ccd

If set, a vector of size CCD-size[1] is returned with coordinate values for the whole detector. The data is then debinned. This may give wrong results if diff_rot is also set.
