General Description

We plan to collect NB 121, NB 219 data for four fields around the center
 of the globular cluster Omega Centauri (NGC5139). We selected the "FixedSkyOffset"
 strategy. We don't have particularly requirement about the seeing: we ask for a
 seeing better than 1". This cluster is observed with an airmass <1.5 from january
 to august, but the best months are april and may. Please note that the finding charts
 have been made using low resolution images collected with FORS1 in the I band. A
 median image was created with a pixel scale of 0.15"/px. We selected these images
 because of the pixel scale similar to that of ISAAC. The green sqare plotted in
 each chart is centred on our pointings, and is somewhat larger than the ISAAc fov.
We decided to use two narrow band filters, because there are many bright sources
 in our fields, namely, we selected the NB 121 and NB 219. The brightest star presente
 in our OBs are:
om_top_let_*: J=9.14, Ks=8.11
om_bottom_right_*: J=9.05, Ks=8.06

Waiver Requests

```
No Waiver Request was submitted
```

Critical Observing Condition Constraints

We ask for airmass <1.4 and seeing better than 1.0". We are observing
 in the NIR, and therefore the Moon does not affect our measurments.

Time-Critical Aspects

We don't have any particular time constraints. The OBs can be executed
 at at any time.
