Next: Jodrell Virgo Survey Up: Minutes of the 1st Previous: Survey Simulations . ... Drift mode: 12s/beam . ... Slow" OTF 6s/beam . ... Fast" OTF, RA-Dec, 3s/beam (drive in RA, step in Dec) . ... Fast" OTF, Dec-RA, 3s/beam (scan in DEC, step in RA) Setup and preliminary analysis: . ... Also look at power spectrum to look for harmonics in baselines: nothing apparent . ... baselines flat . ... Map sensitivity and baseline quality independent of mapping technique when you scan faster than the drift rate. ...
