General Description

The aim of this program is to measure the geometry of the circumstellar
 material around 3 Herbig Ae/Be stars.
Using AMBER's HR-K mode and FINITO fringe tracking, we want to measure the visibility
 both in the K-band continuum as well as in the Brackett-Gamma 2.1661 micron emission
 line.

As DIT, we have specified the recommended value of 3s.  If necessary, please adjust
 this value to the given atmospheric conditions and to the achieved FINITO performance
 in order to optimize the fringe-SNR (using the same DIT for the calibrator and the
 science OB).

The calibrators and their characteristics are (UD diameters from Merand et al. 2005):
HD 94286,  K4/K5III, UD diameter=1.330+-0.018
HD 44891,  K2/K3III, UD diameter=1.423+-0.019
HD 161068, K4/K5III, UD diameter=1.448+-0.019

Do all your OBs comply with the instrument-specific requirements listed on the instrument-specific Phase 2 web page ?

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 ?

```
N/A
```

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

```
N/A
```

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 ?

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 ?

Do you use the same DIT for pairs of science target and associated calibrator?

Are the magnitudes of science target and calibrator within +/- 1 mag ?

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 ?
