General Comments. ( Brief data summary and scan listing )
L band phase-referencing spectral line experiment, observed on 17 Oct 2015. 10 stations participated in the experiment. Below are reported the pipeline results of the LINE correlation PASS. This pass has 1 X 16 MHz subbands, dual polarization, two-bit sampling, and was correlated by using 1024 frequency points per IF/pol, with 2s integrations. Ef was used as the reference stations. The fringe-finder and bandpass calibrators were '3C84' and '3C120'. The target source 'NGC660' was calibrated using the phase-reference source 'J0143+1215'.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.98 . ERI* = 0.98 . (EF=1, WB=1, JB=1, ON=1, MC=1, TR=1, SV=1, ZC=1, BD=1, UR=0.90)

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations. RFIs in Jb, O8, Mc, Tr, Sv, Zc, Bd, Ur.

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available)
Comments.
Scalar averaged Ef-* baselines for LR, each scan plotted separately. No calibration applied yet.

TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot.

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.
Gain amplitude from CL2 table. The Gain values for RCP of Ur are larger than for LCP.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2. No solution for LCP of Ur.

Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot. No solution for LCP of Ur.

Fringe-fit rate solutions
Comments.
SN2 station rate solutions. No solution for LCP of Ur.

Telescope bandpasses
Comments.
Bandpass table 1. 3C84 and 3C120 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3.

Calibrated amplitude and phase against frequency channel
Comments.
Ef-* baselines calibrated with CL3 and BP1. The amp and phase plots self-scale, not necessarily going down to 0 in the case of the amps.
