... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

... Dead time corrections are not considered explicitly in the current version of this task, as it is expected that the EXPOSURE attribute, written to the spectral file by evselect (see also Julian Osborne's proposal regarding exposure-type attributes available on the SOC web server), should take into account dead time effects. arfgen calls the task attcalc internally. ... Note that the intermediate event dataset also contains attributes used to initialise the CAL in the subsequent call by attcalc . ...
