CHECKLIST FOR VLBA DATA CHECKOUT  (Version 6.2   13 January 2006)
      ===================================================================

PROJECT: RDV54  ON 2005Dec14  AT 1759  TO Dec15  AT 1801

JOBS: 2920-2947  CORR. DATE: Jan.20,23-24  #TAPES: 1

STATIONS: SC HN NL FD LA PT KP OV BR MK GC GG HH TC WF WF   #stns _16_

_x_  1. Check tape distribution log(s) against job creation checksheet(s).

_-_  2. If necessary, copy the proposal coversheet and place in project folder.

_-_  3. Make a file called 'sniffer_srcs.lis' with a list of sniffing sources
	 with a format like:   3C84  CONT  1.5 (time in hours between plots)

_x_  4. Run fitex1 or fitex2 <refant> LIST <startfile> <endfile>.

		  refant   startfile   endfile           Source LIST  LINE/CONT

_x_  5. a. Was polarization requested? no    Is it ON? no

       b. Were special coordinates requested? No. But coordinates
	   for three sources were needed from GSFC website:
	 
	  Which sources? 0649-209, 1241+176, 1708+433

	 
  *** Check the plots for the following ***

_x_  1. WEIGHTS: gaps? stations missing? low values?

	Playback is generally good for all stations. BR had a brief
	period of variable weights, but it is not fringing anyway.

_x_  2. AUTOCORRELATION: plots for all stations? consistent amplitudes?

	RFI is prevalent in BBC5, S band, at most sites. Some sites are
	also affected in all S band channels (BR,MK,HN,KP)

_x_  3. CROSS-CORRELATION: plots for all stations?  linear phase solutions?
	
_x_  4. RAPD: good delay, phase and amplitude solutions for all calibrator scans?
	 (range of 20 mHz for rate and 100 ns for delay)

	BR is not fringing due to a subreflector problem (since repaired).

_x_  Give the folder and data tape to local contact.

Additional Notes: 

ON was dropped from correlation; log was in the wrong format.

WZ disk pack NYAL-009 suffered a catastrophic failure, data is
unrecoverable. The data on the other WZ pack appears fine.

FD dish may have been wet from precipitation prior to this run.

MK winds were strong; max gusts up to 50mph. Antenna autostowed a
couple of times.

NL had snow and freezing rain throughout this observation. Tsys are
affected.
