General Description

The idea of the project is to derive the brightness, positional angle
and separation of the binary BS Indi.  We estimate that the separation
of the two components is about 40 mas. The stars themselves are point
sources.  The primary is a K0V star, the secondary is likely to be an
M0V star. The system has a K magnitude of 6.6. We estimate that
the primary has 7 mag and the secondary possibly 8 mag in K.

HD204873 is the visibility calibrator selected from CalVin. 

In the proposal, the we suggested to us UT2-UT3-UT4 as base line.
However, Joao Alves contacted me and said that this is not possible but
UT1-UT3-UT4 can be scheduled. The OBs are thus for baseline UT1-UT3-UT4.

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 ?

```
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 ?

```
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 ?

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 ?
