General Description

Want to measure details of angular diameter and circumstellar
emission in medium resolution both in the continuum (2.1um)
and around a CO line (2.3um).

Expected visibilities will be similar (2.1) or a little lower
(2.3) then the LR_HK case, i.e. possibly for the longest UT
baseline V little less than 0.1

K mag of TX Psc is -0.7

Use of IRIS is accepted and preferred.

Special Calibration Information

Iot Psc is not in the Calvin list, but is a primary VLTI
calibrator (Richichi et al. 2006 submitted) of high
quality. It is at 14.deg from TX Psc. It has been
selected because of its brightness (K=1.0), brighter
than the Calvin calibrators.

Visibilities of Iot Psc, depending on UT baseline,
are expected to be between 0.35 and 0.90.
Diameter UD_K=3.2 (similar in J and H)
sp type K1.5III

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 ?

```
N/A
```

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 ?

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 ?
