General Description

We are searching for the absorption signatures of gas clouds produced
 by
sublimating comets grazing the white dwarf G29-38. We focus on the Ca II doublet
 stellar lines around 393 nm and 397 nm, and try to evidence extra absorptions around
 those two lines. These absorptions should be both variable in wavelength/radial
 velocity and intensity in the vicinity of the stellar lines. We expect the cometary
 absorptions to be around 10% of the stellar line intensity. We aim at obtaining
 a S/N of 70-100 with a resolution of 3 km/s, in order to have a 10-sigma detection.

Critical Observing Condition Constraints

```
None.
```

Time-Critical Aspects

We need that each OB (or each Run in our case) be scheduled some nights
 apart (i.e., no more than one OB per night). However, they can be randomly scheduled
 and do NOT need to be programmed over contiguous nights.
