The variability of those sources previously observed is somewhat greater than observed by Owen et al. (1978); some sources exhibited the lowest flux densities ever recorded at 90 GHz. ... The adopted 90-GHz flux density of DR21 is 17.7 Jy and is based on a 90-GHz brightness temperature of 183.4+-3.4 K for Jupiter (Ulich 1978). ...

The Ryle Telescope was used for some years for monitoring variable sources (in addition to its role in source-surveys related to the Sunyaev-Zeldovitch studies).

... From the main task window, you have only two options ('Add sources' and 'Run omdetect'), either select sources from the image manually, or run the SAS task omdetect to locate sources on the image, by clicking the appropriate button. a) select sources from the image manually (if you are interested only on the main target or few sources on the image ) -- clicking the button 'add source', the task window is hidden and a small window appears as this Figure. ...

. Comment on J0238+1636 . Our data show that in June 1996 the source had an unusually low flux density with an angular size of 0.6". The source is usually highly variable, strong and extremely compact. However, Chen, Zhang & Sjouwerman (1999) also claim the source was resolved with EVN observations at 5 GHz about 8 months after our observation when the flux density was still unusually low.
