Observing Time Calculation for APEX Instruments Artemis and Supercam

Published: 23 Mar 2014

A new observing time calculator is now available for the Artemis 350ТЕm camera offered on APEX in Period 94. This calculator assumes a field of view of 4.7У?2.5 arcminutes, with fully sampled pixels in the 350ТЕm focal plane. The 450ТЕm and 200ТЕm planes are not offered in Period 94. Note that this is only a preliminary version of the calculator, as the full commissioning of Artemis will be performed in June 2014.

The Supercam 345 GHz heterodyne array instrument for APEX does not have a dedicated calculator. However, to estimate the observing time request, the Swedish Heterodyne Facility Instrument (SHFI) on-the-fly calculator should be used, and the time request should be divided by a factor of 13. This factor takes into account the expected 52 operational pixels of Supercam and the slightly higher receiver temperature compared to SHFI.
