Brief data summary
and
scan listing
)
N05L4 was an L-Band Network Monitoring Experiment, combined with a series of test observations for ionospheric calibration. Bright calibrator sources were observed in a phase-referencing style mode to test ionospheric calibration techniques.
Observed on 2005 June 08
128 Mb s^{-1}, 2x8 MHz subbands, dual polarization, 0.5 s integrations, cross polarizations included
Ar, Arecibo: Late start to observing. Data recording started at about08:19 UT, but at that time the telescope was slewing, hence actual data got recorded only by about 08:20 UT. The first scan on the disc has no "scan name".
Cm, Cambridge: Appears to have stopped recording at approximately 04:30~UT, because of an unknown communication problem with the Mk5 system. (Note: from the pipeline results, Cm may be ok until ~7:40.)
Tr, Torun: Used Rubidium frequency standard, because the H-maser was sent to the manufacturer for refurbishment.
Nt, Noto: On June 4 at about 23:00 UT one of the azimuth engines failed. Noto was not operational during N05L3.
Wb, Westerbork: Real time array control system got stuck from 07:33 to 08:45UT. This seems to be a bug triggered by rebooting an offline system from which one of its programs was started. Array calibration is lost from 06:00 to 08:45
The EVN reliability indicator (ERI) for this experiment was
ERI = JB 1 WB 0.65 EF 0.95 ON 1 MC 1 TR 1 NT 0 SH 1 UR 1 CM 0.65 HH 1 AR 0.67
ERI = 0.67
. ERI* = JB 1 WB 0.65 EF 0.95 ON 1 MC 1 TR 1 NT 0 SH 1 UR 1 CM 0.65 HH 1 AR 0.67
ERI* = 0.67

Wb missing data. Ef missing data after 7:05
Telescope sensitivities
from the a priori TSYS and Gain curves (the square of this
number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.
Ar missing because it was not included in the BPASS step.
Fringe-fit phase solutions
(including Parallactic Angle correction).
Comments.
Looks like some poor interpolation schemes happened.
Fringe-fit delay solutions

Comments.
Wb may need flagging at 8:45. Be careful with Ar.
Fringe-fit rate solutions
.
Comments.
Ar has a few very bad points.
Telescope bandpasses
.
Comments.
Ar not included because of source limitations. PI must redo.
