Notes. (1)This is the combined on-source time for the three LoLSS pointings covering NGC 2276. For all three, NGC 2276 is offset from pointing centre and therefore the effective on-source time, factoring in the diminishing primary-beam response, is certainly < 9 h. (2)The relative calibration uncertainty on the flux-scale.
