Extracted Observing Reports for 171.D-0004(A): Night information

Telescope: Antu (UT1)
Instrument: ISAAC
This is a summary of night log information extracted for all those nights which got observations for your run and which are contained in this data delivery.

This information has been extracted from a database which contains information ingested during the nights. The database is also maintained to reflect e.g. a posteriori updates of the OB grading.

This report is structured into two parts:
- breakdown by nights (this page)
- breakdown by OBs.

This page is an extraction of general night information for all nights with OBs in this data delivery. Usually an OB will produce files but there are exceptions, e.g. when an OB is aborted due to degrading conditions. Therefore there might be entries in this nightlog summary which do not correspond to any of the files contained in your data package.

On the other hand there is a small chance of having OBs or files delivered without nightlog entries. The most likely cause could be operational problems during the night.

Date Comments OBs | grade
(this run only)
2003-07-27 UT 23:35 switched to ISAAC due to problem with FORS1
UT 04:43 switched to FORS1
UT 06:20 switched back to ISAAC ... FORS1 did not work again and could not be fixed.
TECHNICAL LOSSES:
FORS1 was given back working while in ISAAC service.
Before switching back to FORS1 (given the dark time and the good seeing) the communication BOB-OT was tested and working ...
However, FORS1 net connection failed again at the end of the first OB (standard) and kept failing despite reboot, reinitalizations, and various checks perfromed by Stephan.

2003-08-21 The DIT=750-s NDR SW dark did not initially reduce. We resubmitted it and it was fine. The
Technical time 01:10 to investigate pattern seen in acquisition images for
Stiavelli, 71.A-0362(A). This was seen a couple of weeks ago and thought to
be due to the moon. However tonight there is no moon and we see the pattern
again. We think it is due to reflections from Mars, which we can see is
visible through the enclosure slit.

2004-02-01 Daytime check: seems like shift-and-add did not work for the offset exposures of OB 149621 [prog. 171.D-0004(A)] in the pipeline, possibly because a few stars are saturated (and therefore could not be reliably centroided on).
Daytime calibrations: Calibration check exposure level ~-10. Will monitor it over the next few days.
Lots of ISAAC technical tests during the day.
