Purpose
Given the starting pixel coordinates of an object on a blue
LRIS image, and destination coordinates, compute and apply the
required telescope move the object as desired. It take into consideration
the gap, tilt and offset between the two detectors.
Works only if the coordinates are taken from figdisp. Use movb_iraf
in case coordinates are taken with IRAF.
Usage
movb [-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) to pixel (300,400)
movb 100 200 300 400
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
