General Description

High resolution Q band spectroscopy of the inner CSE of Betelgeuse. The
 detached dust shell is supposed to be outside the slit.

Sirius is to be observed before and after for (absolute) calibration purposes, with
 more time spent on the integration after the Betelgeuse observation, because of
 a smaller airmass difference. Because Betelgeuse is of course hightest priority,
 I did not use the User Priority Field in the OBs to force this sequence.

Finding charts are in K band, but both Betelgeuse and Sirius should be the brightest
 objects in the FOV also in Q band.

Waiver Requests

Critical Observing Condition Constraints

Because we want to separate flux from the central star from that of the
 dust shell, the seeing constraint (<0.8 arcsec) should be met.

Time-Critical Aspects

```
none
```

Special Execution Requirements

```
none
```

Special Calibration Information

The Sirius OBs will be used for calibration purposes, and should therefore
 be observed as close in airmass and time as possible.

Pre-imaging sources not listed above

---(Empty)---

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 ?

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 ?

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
```

If the provided finding chart is at a different wavelength than the observations, did you clearly describe in the README file how to identify the target?

Did you specify a guide star brighter than V=12mag within a field of r=5arcmin around the science target?
