Important pipeline note

§ Pipeline currently includes a simple, shallow cleaning strategy

§ Algorithm for automatic deeper cleaning now available

pre-November HBA testing

§ baselines <20km, 25 mJy/beam noise for the field shown here

§ default demixing strategy incorrect; new calibration script now available

§ Other fields donot turn out aswell with auto-processing

§ More workneeded toassess qualityof calibrationsolutions...

Recent HBA tests

§ Three regions were observed (weekend of 10-11 November):

§ near L227+69 (MSSS Verification Field)

§ near Lockman Hole (no bright sources in vicinity)

§ near(ish) Cygnus A (to ensure no difficulties)
