... 371Gregory Taylor . ... We persent a catalog of 1274 discrete sources detected during a 5 yr, 6 cm, radio-patrol survey of the galactic plane for variavle sources. ... Seventy-five percent of the sources are weaker than 75 mJy, and as a consequence reliable sources and 27 possible variables were detected, of which 64 % exhibited shirt-term variability. ... A comparison with previous centimeter variability studies suggests the possible existence of two distinnct variability components. ...

. 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.

Next: Status of the BIMA Image Pipeline . ... We describe all the steps of the standard reduction including per pixel error propagation: Bias correction, treatment of bad pixels, flatfielding, and filtering of cosmic ray events. ... We build difference images via image convolution with a technique called OIS (optimal image subtraction, Alard & Lupton 1998), proceed with PSF-fitting, relative photometry on all pixels and finally apply an automatic detection of variable sources. ...
