Estimated Total Execution Time (hours, including overheads)

```
3.0
```

General Description

This observation run is the first of a pair of observations requested
 to be executed with a time interval of the order of 3 months. This part (A) should
 preferentially be executed in May, and the second one (part B) in August, or in
 the beginning of September.

The run is subdivided in two parts, referred to as 1 and 2, that should preferentially
 be executed during the same night. Each part is constituted of an observation of
 the target, and one of the interferometric reference.

The preferred complete sequence for this run is:
Target_1
Reference_1
Target_2
Reference_2

This run is prepared to provide two calibrated visibility triplets of the target.

Time-Critical Aspects

The time interval between the two runs (A and B) should be of the order
 of 3 months in order to sample a long period orbital time-scale. This time interval
 can not be much longer because of airmass constraints. The sidereal time constraints
 are requested to obtain a better sampling of the u,v plane during the observing
 run.

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

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 ?
