The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

We report MIPS photometry of 20 radio-loud quasars and galaxies at 24 and 70 ЮМm (and of five at 160 ЮМm). We combine this sample with additional sources detected in the far-infrared by IRAS and ISO for a total of 47 objects, including 23 steep-spectrum type I AGNs: radio-loud quasars and broad-line radio galaxies; and 24 type II AGNs: narrow-line and weak-line FR II radio galaxies. ... Thus, the measurements at these wavelengths can be used to test the orientation-dependent unification model. ...

... 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. ...
