General Description

Imaging of the star+disk DoAr21 in Q2 band. Two identical OBs integrate
 on source for ~40 min each. Each OB has an associated PSF calibration OB, taking
 17 min each, on the star HD145897. Only ONE PSF calibration per night needs to be
 executed.

The findchart is in K band (as is the source acquisition); the science integrations
 are in Q2 band. In both bands the target should be the brightest in the field. Same
 holds for PSF standard HD145897, although there we use acquisition without imaging
 (preset).

Using the Guidecam tool, a guide star has been identified with magnitude 13.87.

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 ?

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?
