General Description

This is a simple spectropolarimetric program to measure circular 
 and linear polarization in two bright stars. 
The observations can be executed in THIN and even in THICK conditions
with variable seeing. It is most important that a signal level 
of at least 10000-20000 ADU will be reached. On the other hand,
because of varying transparency and seeing, we ask 
the night astronomer not to saturate the spectra if weather conditions
are improving during the exposure.

Waiver Requests

Waiver request to use the non-standard readout mode A,1x1,low has been
 submitted
on July 17, 2005 and granted on the same day.

Critical Observing Condition Constraints

```
No.

Time-Critical Aspects

```
none
```

Special Execution Requirements

Both stars HD 37022 and HD 92207 should not be observed more than once
 
per night.
Circular polarization spectra of
HD 37022 have to be taken immediately (or at least in the same night) after the
 
linear polarization measurements to secure a simultaneous study of the circumstellar
magnetic field and the surface field strengths and distribution.

Special Calibration Information

We submitted two OBs for a standard star for circular polarization. 
They can be observed randomly over the period.
We expect that the linear polarization standard will be taken corresponding
to the Paranal calibration plan.
