Estimated Total Execution Time (hours, including overheads)

```
6.3
```

General Description

This run should start as soon as possible after the evening sunset of
 UT 2007-10-10, and then observe continuously the target for 6.3 hours.

The nominal time for the OB is longer than 6.3 hours, however, p2pp has overestimated
 the overhead since several of the offset have zero displacement.  Therefore, the
 real observing time is expected to be much less.  Please, just abort the observations
 once 6.3 hours have been reached.

See critical observing constraints section for important condition on seeing.

Waiver Requests

A "Long OB" waiver was granted (ID# 080.C-0406A.01)

Critical Observing Condition Constraints

We require a dry (<50% percentile) and photometric atmosphere, but
 we have no constraints on the seeing.

  It is critical to avoid the persistance effect which, according to the SINFONI
 manual, appears after ~10K ADU.  The DIT we indicate in the OBs is optimized -according
 to the ETC- for a FWHM V-band seeing of 0.9".
  We propose two possible solutions if counts rise above 10k ADU:

  * bad AO correction.  This is the ideal solution since nothing else will need
 to be adjusted and there will still be minimum overhead time.
  * reduce DIT and increase NDIT.  The idea is to keep NDIT*DIT=constant.  Please,
 if possible, avoid doing this more than once during the run

Non-time-critical run B can be executed before or after time-critical Run A.

Time-Critical Aspects

Ideally, this 6.3 hours continuous observations should start at 2007-10-10UT22:30,
 however the Sun will still be up that day.   Therefore, we request the beginning
 of the observations as early as possible into twilight.
