===================================================
Results of the tests done on the 26th january 2002
to test the ag_dither scripts of INGRID
===================================================

a) A careful determination of the rotator center 
   was done and a pointing-calibrate with 7 stars 
   on the sky was done.

b) I runned the following script:

#!/usr/bin/csh -f -x


user "ENTER APERTURE 1 240 0"
user "ENTER APERTURE 2 -240 0"
user "ENTER APERTURE 3 0 240"
user "ENTER APERTURE 4 0 -240"
user "ENTER APERTURE 5 0 -3"
user "ENTER APERTURE 7 3 0"
user "ENTER APERTURE 8 -3 0"
user "ENTER APERTURE 9 0 3"


set exp = $1
set coavgs = $2
set xoff = $3
set yoff = $4
set gal_name = $5

***The exposure time was 25s and the number of coaverages was 3 ==> 5min/dither

***While observing, the zenital distance of the object was: 
   ZD= 38.550628 (AZIMUTH = 221.803427)

***The centroid of the star appeared in the following position
   on each image:
