SABOCA observing time calculator (Version 1.1)
You can either calculate the RMS for a given integration time, or calculate the integration time needed to reach a certain RMS.
The estimated sensitivity of the array is 200 mJy sqrt(s).
Scanning area should correspond to the area covered by the scanning pattern. For a single point source, this value should be set to 0. Note that the unit is square arc minutes (arcmin2). The total area of the resulting map will be uniformly covered over the scanning area if it is larger than the array size. For details, see http://www.apex-telescope.org/bolometer/laboca/observing/
The calculated integration time does not include any overhead times. This overhead includes setup, target acquisition, software setup, data transfer time (writing the FITS file), telescope slewing time, and calibrations (skydips, focus, pointings and flux calibration). In order to facilitate the calculation of the total observing time needed to achive a certain goal in rms noise, a time calculation including an avarage combined overhead of 90% is also presented by the observing time calculator.
Line-of-sight opacity of 1.3 has been assumed. A line-of-sight opacity of 1.3 at an elevation of 60 degrees corresponds to a PWV of 0.5 mm
