There is usable data for most of this project.
There is a blank in the project name, I dont know
what its called in the archive - I could not get
to it by name and got it by timerange instead.
The '40-min time jump' happened on the CMP - its in the
log. Good data (IFs A,C) continued till 03:46:40 IAT,
after which in mid-scan the phases ramped off before
all VLA antennas went incoherent on all IFs till 04:15.
Then there is a data gap of 15 min or so after fringes
resume. (Pete said he did nothing but watch - the CMP
recovered itself). EVLA antennas continue unperturbed,
as expected.
IFs A,C: VLA and EVLA were all coherent, except for the
time above.
IFs B,D: VLA, EVLA coherent in mutually exclusive subsets
for the whole time. In addition, for the whole time:
EA 24 had no fringes on IF B
EA26 had no fringes on either B or D.
