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

Telescope: Melipal (UT3)
Instrument: FORS1

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

This is a summary of OB 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 OBs (this page)
- breakdown by nights.

This page lists all the OBs and their related entries in the Paranal night logs. For each OB, the user-defined name, the target, the execution date(s) and time(s), the grade, and comments are listed.

Grade is set by the on-site observer, based on the user requested observing conditions (the OB Constraint Set) vs. the actual observing conditions. Its possible values are listed below.

Whenever possible, OBs with execution status "C" are repeated. Thus, some of your OBs may have been executed multiple times. Common reasons for NOT re-executing out-of-specification OBs are:

- lower priority run, no time left in semester
- target has set
- date constraint cannot be satisfied
- pre-imaging OB, data OK for MOS preparation.

Each OB entry has a link to a detailed plot of the ambient conditions. There is also the QC0 report listing ambient conditions file by file.

If you have questions about the execution status of your OBs, please contact the ESO User Support Group (usg-help@eso.org).

Note: There is a small chance of mismatches between delivered OBs/files and nightlog entries. The most likely cause are missing entries due to operational problems during the night.


OB grades: A)Fully within specifications B)Mostly within specifications C)Out of specs - Repeat X)Uncertain/Not Applicable
