ESO Comments
-  1999-07-12 : There is only one very faint guide star in the field - therefore we had problems with the field stabilization. For frame 3 : no guide star after offset preset the telecope, I don't know the actual position ! (it doesn't seem to have consequences, except perhaps in the alignment process)

Comments
-  1999-07-12 : 24 frames for the superflat. Shift errors in alignement process are high for frames 3 and 6
