The time allocation is as follows: c131a : Eu 136 1700(16/05)-2147(16/05) 512+1024 Mbps; Eb Yb Pv Pb On mt001a: Eu 136 2200(16/05)-0522(17/05) 1Gbps; Eb Yb Pv Pb On gr034 : Eu 137 0530(17/05)-2147(17/05) 512 Mbps; Eb Yb Pv Pb, On stops 15h US 137 0530(17/05)-1800(17/05) 512 Mbps; VLBA mt001b: Eu 137 2200(17/05)-0522(18/05) 1Gbps; Eb Yb Pv Pb only mt001c: Eu 138 2315(18/05)-0522(19/05) 1Gbps; Eb Yb Pv Pb only Schedule Location: ------------------ c131a: ftp://ftp.mpifr-bonn.mpg.de/outgoing/p459kri/3mmmay13/c131a mt001a,b,c: ftp://ftp.mpifr-bonn.mpg.de/outgoing/p459kri/3mmmay13/mt001 gr034: http://www.vlba.nrao.edu/astro/VOBS/astronomy/may13/gr034 You can elso retrive the schedule using anonymous ftp, or if you go to the GMVA website (http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/) and check the link -> Session -> Observing Session for May 2013. Recording mode: ----------------- All recording is done using the MK5A and MK5B systems. c131a: 512 Mbps + 1Gbps, dual pol gr034: 512 Mbps, dual pol mt001: 1 Gbps dual pol (part a,b,c) Phasecal: --------- Phasecal should be ON (where possible) Calibration: During the experiments, please perform regular antenna- and ------------ system-temperature measurements in gaps between VLBI scans. If possible, please provide measuremnt of atmospheric opacities. Please provide K/Jy values and gain-elevation curves. For Europe: If you cannot measure Tsys continuously (every 60-120 sec), it should be measured before AND after each VLBI scan: Please modify your station procedures, so that Tsys is measured in PREOB and in POSTOB. Please insert correct CALTEMP in your station procedure. In gaps between VLBI scans, antenna temperature measurements of the VLBI sources should be done (cross scans or on-offs).
