GENERAL This part of EG031 comprised 8 stations with 1 2MHz IF (DC edge 6667.3MHz) with 1 polarization (LCP). There were 2048 frequency points, and integration times were 2s. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, only NRAO530 was fringed. A SOLINT of 2.0min was used.

The EVN reliability indicator was ERI=1.0. ERI estimates the ratio of good -to- expected visibilities. The value of 1 essentially means that there were no systematic losses due to playback. The On RFI near the middle of the band that may affect tracing the full line shape on On-* baselines wasn't explicitly included in this calculation. /// POSSM_AUTOCORR 21p of plots, one for each scan. RFI and/or internal birdies in On, Tr. See cover letter for more details. /// VPLOT_UNCAL full-experiment Ef-* baselines, no calibration applied. /// POSSM_UNCAL 21p of plots, on for each scan for Ef-* baselines. /// TSYS TY1 table. There was no Da Tsys info because of the data transmission over the micro-wave link -- set to 1. /// GAIN gain from CL2 table. /// FRING_DELAY SN2 station delay solutions. Some obvious outliers (On RCP at ~2100). Evident deviations between residual delay for B1530 & J1613. Noticeable slope for Ar. /// FRING_RATE SN2 station rate solutions (a few obvious outliers that affect automatic AIPS-determined phase-connection decisions). /// FRING_PHAS CL3 station phase solutions. some phase-connections are clearly affected by RATE outliers (Jb LCP at ~2030). /// BANDPASS bandpass table 1. Only NRAO530 was used for bandpass calibration. /// VPLOT_CAL Ef-* baselines calibrated with table CL3. /// POSSM_CAL 297p of plots, showing Ef-* baselines calibrated with CL3 and BP1. The edges of the band have been apparently overcompensated in the bandpass correction process. /// IMAPN Natural-weighted (dirty) maps for the calibrators B1530, J1613, and J1516 (the latter two having very few scans -- 1 for J1516 leading to a very elliptical beam indeed) /// IMAPU Uniform-weighted (dirty) maps of the above calibrators. /// CALIB_PHAS1 For each of the calibrators (B1530, J1613, J1516), plots of post-SPLIT tables SN1. J1516 had only 1 scan. /// CALIB_AMP2 As above, but for the post-SPLIT table SN2 /// SENS CL4 gain-amp. /// CLPHS For each of the calibrators (B1530, J1613, J1516), 24p of plots showing closure phase for the triangles (not just Ef-*-*). /// VPLOT_MODEL For each of the calibrators, plots of amp/phase on Ef-* baselines calibrated with (post-SPLIT) table CL3, with a model-line overplotted. J1516 has only 1 scan, so its time-axis has quite high resolution indeed... /// UVCOV For each of the calibrators, a plot of the u-v coverage. (comparing J1516 to the EG031_2 pipeline shows the effect of replacing Cm with Mc on the 'snapshot' u-v coverage) /// UVPLT For each of the calibrators, a plot of amp vs. |uv| distance. /// ICLN For each of the calibrators, a CLEAN map resulting from the automated fringing/self-cal pipeline script. ///
