Extracted Observing Reports for 69.D-0462(C): Night information

Telescope: Melipal (UT3)
Instrument: FORS1

Created on 2004-04-14 14:22:31
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.

2002-04-22 Despite the weather conditions (bad seeing, thick clouds, and strong wind from the North), after VLTI Coude commissioning, I kept observing and classified "C" since nothing more suitable was found in the queue. Time spent gathering useless data or during acquisition has been counted as weather loss.
