<images> | File to assign to or modify |
[dump=<listfile>] | Dumps the (processed) Eulers to a textfile. If used, Eulers are NOT written to <images> |
[spiderout] | Used with 'dump' to produce Spider style Eulers (phi,theta,gamma) |
[imagicout] | Used with 'dump' to produce Imagic style Eulers (alpha,beta,gamma) |
[mrcout] | Used with 'dump' to produce MRC style Eulers (theta,phi,omega) |
[sgiout] | Used with 'dump' to produce IRIX Explorer angles (Q,n1,n2,n3) |
[fromfile=<listfile>] | Listfile contains 'N alt az phi' in degrees |
[collapse=<angle>] | If alt>angle -> 90, alt<angle expanded to reach 90 |
Description
This program is used to work with Euler angles present in the image header.
It can be used to set angles from a text file, dump existing angles to a text file,
or modify the angles in one of several specific ways.
'collapse' allows compensation for the problem that sometimes the equatorial Eulers (alt=90)
get pushed up towards the pole (alt=0). This will linearly 'collapse' the angles back towards the equator.
