Click on project # for the Tsys/gain info, and results / feedback etc.
Date	Project #	Network	P.I.	RX Used	Correlator	Brief Comment
26-Apr-01	TA025	VLBA+Ar	J. Romney	L-Narrow	Socorro	Fringes Found, X-pol, missing trk 14 and ~7--micron head-positioning error
15-Aug-01	TA026	VLBA+GBT+Ar	J. Romney	S-radar	Socorro	Fringes found after many trials which finally a 700 mu head positioner shift, all tracks Fine
07-Sep-01	TA027	VLBA+Ar	J. Romney	L-Narrow	Socorro	Fringes Found, with 700 micron shift. All tracks O.K.
15-Sep-01	BM159b	VLBA+Y+Ar	E. Momjian	L-Narrow	Socorro	Fringes Found after 700 micron + ~460 micron in the first pass shift. All tracks OK.
05-Oct-01	SC01C3	EVN+Ar	Tony Foley	C-band	JIVE	No Playback. This was a dual-head recording test. Some EVN stations had set-up problems. The run was rescheduled. AO couldn't join in.
New Headcal done with corrected procedure. 700 micron shift removed
18-Oct-01	W323D	VSOP+Ar+etc.	D.L. Jones	C-band	Socorro	Track#18 dead, ch2 dead for even passes. Fringes detected on Ch 3 and 4 (+ on ch2 in odd passes). Headstack enableing commands had errors which needed correcting online.
19-Oct-01	W323C	VSOP+Ar+etc.	D.L. Jones	C-band	Socorro	Same as above
09-Nov-01	ED018A	EVN+Ar	J.-F. DESMURS	Cb (5cm)	JIVE	Playback problems. A few EVN stations had freq-setting problems. No more news
10-Nov-01	ED018B	EVN+Ar	J.-F. DESMURS	Cb (5cm)	JIVE	--- no news ---
