=============================================
Tests on sky on the 21 and 22nd of March 2002
=============================================

--------
21 March
--------

**We have measured that the array has a rotation of +1 deg and the plate
scale is now 0.244"/pix (it was 0.238"/pix before).

**Bad seeing, therefore it was not possible to say anything regarding
image quality

**Vignetting in the upper part of the array (~60 pix)

**The motors did not work properly (the new 'Phytron' motors
which were installed inside INGRID. We were forced to 
observe with only one filter each night to avoid incorrect positions.

--------
22 March
--------

**This was the first night of a run, but the seeing was very good and
we saw bad image quality on INGRID. Stars were ellongated by ~20-30%.

**After analyzing the images, it was clear that there was a problem of 
coma in the wht. This was fixed in April 2002 by tilting the secondary 
mirror of the wht.
