!! Acquisition Images Changed lines 4-9 from:
** do a PSF fitting to the science acquisition image using the calibrator image. This can be useful to look for extended emission. to:
** do a PSF fitting to the science acquisition image using the calibrator image. This can be useful to look for extended emission. ** get an impression on the single-dish flux for sources where the single-dish spectra are too noisy to give useful information !! MACAO * Moon distance: no definite answer how far away moon must be, depends on conditions, brightness of guiding star and distance of star from source (when offset guiding). Information (according to Rivi): a 14 deg distant V=16.5 star at full moon is probably impossible, 30 deg distance is probably OK. But it hasn't been tested yet. April 30, 2009, at 19:51 CET

- Added lines 1-3:
* Always take acquisition images (both for the calibrator and the science source), especially for weak sources since it will allow you to ** check the beam quality (beam A vs. beam B) ** do a PSF fitting to the science acquisition image using the calibrator image. This can be useful to look for extended emission. |
