General Description

We want to map the host galaxies of quasars at z<0.2 from Hbeta to
 Halpha to map velocity structures, ionisation situation and model stellar populations.
 Most objects need two grism coverage for the target wavelength range and some OBs
 complement existing data. The observations are just slightly dithered to be able
 to remove bad fibre signatures. The dither distance is chosen to be 1.5 spaxels,
 so that we get a sub-sampling of the spaxel grid by 4 dither points with 1.5 pixel
 distance. We add a short sky exposure at the end of the science block, in case that
 most of the FOV is actually filled by the science target. The individual exposures
 should be substantially below saturation, but still background limited.

Waiver Requests

We have an approved waiver to extend the maximum OB duration to 1:25h
 submitted on 14 January 2009 and approved on 15 January 2009.

Critical Observing Condition Constraints

None beyond the constraint set for small field of view (seeing <1.0",
 max. thin cirrus, airmass<2.0, moon grey) and for large field of view (seeing
 <1.2", max. thin cirrus, airmass<2.0, moon grey).

```
N/A
```

Did you specify suitable guide stars for all your OBs using Guidecam ?

```
N/A
```

Did you check that the chosen guide stars are suitable for all the offset positions and that they do not produce unacceptable vignetting of the field of view ?
