|Densification of the VLBA calibrator list (BP192)||Regular VLBA geodetic observations (RDV)|
|The schedule is generated automatically by the array operator in a filler mode during gaps between high priority projects. If your requested source will be visible during allotted time, it will be observed. Since BP192 is observed only during gaps of high priority projects and it competes with other filler projects, it is impossible to predict when and even whether your requested source will be observed. Sources at popular ranges of local sidereal time and at low declinations has less chances to be picked up.||Scheduled manually on a fixed dates six times a year. Sources at all LST get the equal chance to be observed|
|Observed at 7–10 VLBA stations at [4.16, 4.64] and [7.36, 7.84] GHz simultaneously at 2048 Mbit/s in one scan 60 seconds long.||Observed at VLBA, plus 5–10 non-VLBA stations at [2.23, 2.37] and [8.41, 8.90] GHz simultaneously at 256 Mbit/s in one or two scans 300 seconds long.|
Placed in the queue within 1 hour of approval.
Raw correlator output of projects observed under BP192 program
will be accessible from
||Scheduled within 2–4 months. Analyzed within 1–2 months upon observations. Results of analysis are source positions.|
|No proprietary period. Correlator output in FITS-IDI format is publicly available immediately.||Correlator output is locked for 1 year. Publicly available after one year.|

If you need a phase calibrator for your observation, please first check the VLBI Calibrator Search Engine. If you did not find a suitable phase calibrator, please fill the form below and submit your request.
Your request will be directed to the NRAO Scheduling Officer. You will be notified whether you request has been approved, and if yes, for which program, BP192 or RDV.Back to Astrogeo Center main page.
