However, the Effelsberg staff is willing to *test a new low-frequency receiver that will be installed end of May. *The frequency setup for Effelsberg may have to be modified later, but *this will be done directly with Effelsberg staff. * *The station file "sta.sess211.dat" provided by Bob Campbell is needed *to run SCHED. * * *The following warnings from SCHED are expected and can be ignored: * *SHORTN: WARNING - Source names longer than 8 characters used. * *SETFCAT: In setup: vlbaevn.9050cm.256 * Station VLBA_* * Only 58.00 of 64.00 MHz total bandwidth is within the IFs * in the setup file before any FREQ or DOPPLER shifts. * *SETFCAT: In setup: vlbaevn.9050cm.256 * Station JODRELL1 * Only 60.00 of 64.00 MHz total bandwidth is within the IFs * in the setup file before any FREQ or DOPPLER shifts. * *SFINFO: **** WARNING **** * The setup file: * vlbaevn.9050cm.256 * has unmatched channels at different stations. * *SFINFO: **** WARNING **** * The setup file: * vlbaevn.9050cm.256 * has duplicate channels. * *CHKSCN: 25 scans had more than half the antennas arrive on-source * after the start time. * This could be normal if using duration scheduling with small gaps. * *STALST: WARNING - A station has zero axis offset, which is unlikely. * * * * *frequency setup: *---------------- * *At the VLBA we observe at 90cm and 50cm simultaneously, with a *non-standard bitrate for this combination of 256 Mb/s. Narrow (4MHz) *RF filters are used at 50cm to avoid the danger of strong RFI *saturating the receivers. This means that only 50% of the 8 MHz width *of that subband will be used. This is intentional. * *Jodrell does not cover the full range at 90cm. We duplicate a lower *band in the last pair. * * * *correlation: *------------ * *This will be correlated in Bonn with the software correlator *DiFX. Because many passes with different parameters will be needed *over a couple of months, we will (after a first standard correlation) *copy the data to local disks and later correlate from files. * * * *sources: *-------- * *target pulsars * * B1845-01 * B1859+03 * B1933+16 * B1937+21 * B1946+35 * *control sources (also pulsars) * * B0329+54 * B0531+21 * B1929+10 * * *calibrators and fringe finders (from Rampadarath, Garrett & Polatidis 2009) * * 3C286 (J1331+3030) 6.29 Jy (also recommended by VLBA status summary) * 3C380 (J1829+4844) 2.95 Jy * * *weaker ones for Arecibo * *! selected from http://www.vlba.nrao.edu/astro/calib/vlbaCalib.txt *! and literature search (+NED) for 90cm fluxes * * J1816+3457 weak, but okay for Arecibo * J1832+1357 relatively weak, but point-source * J2018+0831 relatively weak, but point-source * * *We do not need phase-referencing. With gating the pulsars should be *bright enough for self-calibration. Therefore we schedule simple *blocks of targets and control sources, plus fringe-finders every now *and then. * *Gaps are included in the middle of scans to avoid that all telescopes *have to wait for the slowest one. * * *Thanks to everybody who helps making this experiment possible! * * *------------------------- end ------------------------- * target_correlator = BONN; * * integr_time : 1.000 s * number_channels: 256 * number_antenna : 14 * cross_polarize : Yes * weight_func : UNIFORM * distrib_medium : FTP * source_pos_cat : SCHEDULE * distribute_to : * AIfA, Uni Bonn * Auf dem Huegel 71 * 53121 Bonn, Germany * corr_notes : * Parameters will be discussed directly with correlator staff. * Some correlations at AIfA.
