General Description

This is a simple spectropolarimetric program to measure magnetic fields
 in bright 
pulsating stars over the rotation period. Since our targets are very bright, the
 observations 
are very sensitive to seeing fluctuations. It would be good to check the level 
of signal during the exposure to avoid saturation. The observations can be executed
 even in THICK conditions, if the exposure time is properly adjusted to achieve an
 ADU level of at least 10000-20000.

If there is not enough time to complete observations for all targets, please try
 to complete all epochs at least for a few of them.
Since we need good rotation phase coverage, the same target should not be observed
 twice 
during the same night, but can be observed on consecutive nights.

Waiver Requests

We submitted a waiver request (084.D-0230A.01.WAV) to skip finding charts
 for all targets apart from HY Vel where 
a rather bright companion is visible in the field of view.
Further we asked to use the non-standard readout mode 200kHz,1x1,low.

Critical Observing Condition Constraints

```
none
```

Time-Critical Aspects

The same target should not be observed twice during the same night.

Special Execution Requirements

```
none
```

Special Calibration Information

To reduce calibration time we ask only for one arc spectrum and one flat
 for each respective night when our program was observed.
We ask for only one set of biases for the whole semester.
