Time allocation criteria

All proposals are judged and ranked solely on the basis of scientific merit by our TAC. OPTICON proposals are judged by the OPTICON TAC.

Important information

1. The available instruments are: LN2 CCD, ATS, and RISE2. For technical reasons the MES-AT spectrometer and the VEC camera are not available this year.

2. The Exposure Time Calculator (ETC) for the LN2 CCD is similar to that of the LN/CCD. Information about the ATS exposure times and stellar magnitudes can be found in the ATS Cookbook.

3. Due to collaboration agreements and commitments the RISE2 camera can be used for any project except for exoplanets.

4. There is no running or accommodation cost for the observers.

5. There are standard rides to the Observatory before and after each observing run. The visitor observers may be transfered by the observatory's vehicle but they have to inform us well in advance. Special rides are not available, it is the observer's responsibility to reach the Observatory on time. The visitor observer cannot stay at the Observatory before or after the observing run.

6. The Observatory does not provide meals to the visitor observers, only drinking water. It is the visitor observers' responsibility to arrange his/her meals. Note that before each observing run the observers may purchase food from the city of Kalavryta.
