seteulers

Will assign Eulers from a text file or modify existing assignments (IMAGIC only)

seteulers <images> [dump=<listfile>] [spiderout] [imagicout] [mrcout] [sgiout] [fromfile=<listfile>] [collapse=<angle>]

Parameters:


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.

<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
