- version of movb but with coordinates from figdisp to ds9 (f2d).
Purpose
Given the starting pixel coordinates of an object on a blue
LRIS image as measured using FIGDISP, and destination coordinates as output
from the routine check_boxesb (DS9 or IRAF), compute and apply the
required telescope move the object as desired. It takes into consideration
the gap, tilt and offset between the two detectors.
Works only if the star coordinates are taken from figdisp, and the box
coordinates as measured with check_boxesb in IRAF with DS9.
movb_f2d means
are measured in FIGDISP for the star and shifted "2"
coordinates measured with "d"s9 / IRAF/ ximtool etc.
Usage
movb_f2d [-n] x1 y1 x2 y2
Arguments
-n = no move, only print the required shift
x1 = starting column location of object [pixels]
y1 = starting row location of object [pixels]
x2 = ending column location of object [pixels]
y2 = ending row location of object [pixels]
Output
Exit values
0 = normal completion
1 = wrong number of arguments
2 = arguments not valid floating-point numbers
Example
1) Move a target at pixel (100,200) in figdisp to figdisp pixel (300,400)
movb 100 200 504 400
2) Display the telescope move required to shift a target at
pixel (100,200) to the pixel (300,400) without moving the telecope
movb -n 100 200 300 400
