General Description

Observations of the inner dust disk of 4 Herbig Ae stars, of which 1 is
 a UX Orionis variable star. In the first place, we intend to determine the disk
 inclination. Second, we will try to derive the spatial extent of the inner rim:
 the vertical scale from the more edge-on system (which the UXOR is expected to be),
 the radial extent from the less-inclined systems (i.e. the other targets). Three
 simultaneous visibilities AND closure phase measurement are needed to meet these
 science goals.

Time-Critical Aspects

Targets HD250550, HD35929, HD37806 and their calibrator stars are observable
 throughout the entire P78. HD95881 and its calibrator are only observable during
 the last months of P78. 
This is indicated in the respective OBs.

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 ?
