GENERAL ET038D. K-band EVN experiment, observed on 12 June 2018. The data rate was 1024 Mbps (8x16 MHz subbands, dual polarization, two-bit sampling). The target IC485 was calibrated using the phase-reference source J0802+2509. DA193 was observed as calibrator and fringe finder.
7 stations participated. /// POSSM_AUTOCORR Each scan plotted separately, all stations. /// VPLOT_UNCAL Full-experiment for Ef-** baselines, no calibration applied. A 1.5 minute plot-averaging was used. /// POSSM_UNCAL Scalar averaged Ef-** baselines, each scan plotted separately. No calibration applied yet. /// POSSM_CPOL /// TSYS TY1 table, each IF/pol on a separate plot. /// GAIN Gain amplitude from CL2 table. /// FRING_DELAY SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot. /// FRING_RATE SN2 station rate solutions. /// FRING_PHAS CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2. /// BANDPASS Bandpass table 1. DA193 was used for bandpass calibration. /// VPLOT_CAL Full-experiment for Ef-** baselines, calibrated with CL3. The 1.5-min plot-averaging still applied. /// POSSM_CAL 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. /// IMAPN /// IMAPU /// CALIB_PHAS1 Plots of post-SPLIT tables SN1 for the sources that have been individually fringed. /// CALIB_AMP2 As above, but for the post-SPLIT table SN2. /// SENS CL4 gain-amp. /// CLPHS Separate files per (fringed) source, showing closure phase plots for all the triangles. Only stokes=I shown. /// VPLOT_MODEL For each (fringed) source, plots of amp/phase on Ef-** baselines, calibrated with (post-SPLIT) table CL3, with a model-line overplotted. /// UVCOV For each source, a plot of the u-v coverage. /// UVPLT For each source, a plot of amp vs. |uv| distance. /// ICLN For each source, a CLEAN map resulting from the automated fringing and self-cal iterations in the pipeline script. ///
