General Comments. ( Brief data summary and scan listing )
N05L2 was an L-Band Network Monitoring Experiment, combined with a series of test observations for ionospheric calibration. 3C273B was observed twice for FTP fringe testing. Other bright calibrator sources were observed in a phase-referencing style mode to test ionospheric calibration techniques.
Observed on 2005 June 02
256 Mb s^{-1}, 4x8 MHz subbands, dual polarization, 0.5 s integrations, cross polarizations included
Tr, Torun: BBC\# 3 was unlocked all the time, resulting in loss of data. Used Rubidium frequency standard, because the H-maser was sent to the manufacturer for refurbishment.
EF missing from scan 1.

The EVN reliability indicator (ERI) for this experiment was ERI = JB 0.9 WB 1 EF 1 ON 0.66 MC 1 TR 0.88 NT 1 SH 1 UR 1 CM 1 HH 1
ERI = 0.90
. ERI* = JB 0.9 WB 1 EF 1 ON 0.66 MC 1 TR 0.88 NT 1 SH 1 UR 1 CM 1 HH 1
ERI* = 0.90
. (JB=1, ON=0.8 ...)
