Phase misclosures in Mark-3 and Mark-4 data

Phase misclosures were computed for some triangles. Misclosures are presented in plots. Argument: time from the beginning of the session in hours. Value: phase misclosure in phase turns.

Mark-4 data. The new experiment na410 $01MAR06XE

Baseline baseline Ag/Ny/We X-band

Baseline baseline Ag/Ny/We S-band

Baseline baseline We/Ma/Ny X-band

Mark-3 data. Old experiment na299 $99JAN19XE

Baseline baseline Ag/Ny/We X-band

Baseline baseline Ag/Ny/We S-band

Baseline baseline We/Ma/Ny S-band

Mark-4 data. Experiment na406 $01FEB06XE

Baseline baseline Ag/Ny/We X-band

Baseline baseline Ag/Ny/We S-band

Mark-4 data. Experiment na407 $01FEB13XE

Misclosure for GAO ( GILCREEK/ALGOPARK/NYALES20 ) during na409 $01FEB27XE:

Mislosure at X-band obtained by Solve Units: phase turns.

Mislosure at X-band obtained by aedit Units: degrees (commands: close; plot cphase)

Mislosure at S-band obtained by Solve Units: phase turns.

Mislosure at S-band obtained by aedit Units: degrees (commands: close; plot cphase)

We see that phase misclosures of the new experiments processed by Mark-4 correlator and post-correlator software are different: there is a permanent misclosure. I found that ALL experiments starting from 01FEB13XE have this problem and did not find any experiment with this problem before it. Experiment na407 01FEB13XE was released on 2001.03.05-18:17:38. The previous experiment na406 01FEB06XE was released on 2001.02.23-17:41:43...
