General Description

This is a standard MIDI observation, the target has been resolved on similar
 baselines, and is expected to show ~0.3-0.5 
visibility amplitude. Note that there is a very strong and broad silicate absorption
 around 9.8, where we don't expect to 
get fringe data (SNR too low). This shouldn't affect the fringe tracking however.
 Acquisition should be done in a narrowband
filter close to 8 micron for this absorption feature, but I believe this is standard
 anyway. Within the 2arcsec diameter FOV, 
the source will be the brightest.
I use 8000 frames phot exposure (more than the recomended 6000) for the science
 target, because of the deep silicate absorption 
feature.

Time-Critical Aspects

Limited HA-ranges (3hrs) are given to ensure the right uv-sampling.

Special Execution Requirements

Special Calibration Information

If the observing efficiency is high enough to brackt the science observations
 with two calibrator measurments, please do so 
to increase the calibration precision. For this reason, two cal-OB's are given.

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing Category for each Observing Template ?

```
N/A
```

Do all your finding charts comply with both the general and instrument-specific Phase 2 Web Pages ?

If you submitted OBs for standard stars, did you specify the magnitude and spectral type of all standard stars in the OBs ?

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

```
N/A
```

If you have preferences which OBs should be executed first, did you make use of the User Priority field in the OBs ?

```
N/A
```

If this is a run that requires coordinated observations with other facilities, did you give proper instructions in the Time-Critical Aspects Section ?

```
N/A
```

Did you indicate for each science star OB the corresponding calibrator star OB (and vice versa) in the 'Instrument Comments' field ?

Did you check that your chosen calibrator is bright enough for the instrument mode used ?

If you use calibrator stars which are not in the CalVin database, did you specify their characteristics in the README file and in the OBs ?

```
N/A
```

Did you verify that your coordinates are as accurate as possible (2Mass coordinates recommended) and that they include proper motions if available ?

Did you specify the LST range of the calibrators such that they cover the range from 30 min before the start of the LST range of the science target to 30 min after the end of the LST range of the science target ?
