Target & polarization standard list

The target list contains sources with high (normally brighter ones) and low (normally fainter ones) priority. The targets with high priority shall be observed each night once whenever possible, the sources with low priority 1-2 times per run. As time goes by sources will be added and/or removed. Priority may also change depending on the brightness level and/or due to an ongoing multi-wavelength campaign and or an alert.

For each of the targets a separate link is provided, which gives finder charts, typical integration times etc. For convenience 2 or 3 different finder charts are provided. One with a very large field of view (30' * 30' in case of mis-pointing of the telescope), one with a 10' * 10' field of view (mostly from the WEBT-page (via link GASP source list) or the finder chart compilation at the Landessternwarte Heidelberg and one with a snap-shot of the GUI of the autoguider. The latter allow to easily pick up a good guide star (only relevant for sources with integration times > 2min). More information on the sources can be found here . The finder charts etc. are updated as observations progress.

Upcoming GLAST or other campaigns can be found below the target list.
