Hi,
I would like to use the “QSONumberCountsMetric” from the metric analysis framework (MAF) and normalize this number by the sky area.
For example, for the COSMOS deep-drilling field (DDF). I find this metric from the website: baseline_v4.0_10yrs (baseline v4.0).
However, since the DDF pointings are dithered, I would like to understand whether this number should be normalized to the area of the telescope field-of-view (9.6 deg2) or to the area swept by the dither pattern (rough visual estimate yields ~18.6 deg2).
This would be trivial to estimate from the already plotted maps, but it seems that no information on the scale is given.
Thank you very much in advance.
Best,
