This is because we use an un-standard frequency setup. For this two epochs we will observe during about two hours the 28SiO v=2, j=2-1 and 29SiO v=0,j=1-0, lying respectively at 85640.456 and 85759.132 MHz. These frequencies are outside the standard frequency setup at 3mm (v3mm_a [86000,86500] setting for the 28SiO v=1, j=2-1). We successfully used this un-standard frequency setup in previous observations (see project BM154). To avoid problems, we included the setup directly in the key file. The corresponding setup that it would be necessary to include in the freq.dat file, would be something like: Name = v3mm_c Station = VLBA Priority = 0 rf1 = 85500, 85500 ifname = D, D rf2 = 86000, 86000 fe = 'omit','3mm','omit','3mm' pol = LCP, LCP lo1 = 85000, 85000 syn(1) = 13.6 syn(2) = 15.1 syn(3) = 11.9 note = 'Freq setting for 28SiO v=2, j=2-1 maser, JFD 19Nov02' / Please, can you tell me that you are agree with this frequency setting. Best Regards, Jean-Francois Ps: The warning about the read back tests are not really relevant as this antenna (Sc,Hn and Br) are observing only at the begining and the end of the observation (only the part at 7mm). -------------------------------------------------------------------------- Jean-François DESMURS Observatorio Astronomico Nacional Post-Doc Apartado 1143 email : desmurs@oan.es 28800 Alcala de Henares Phone: (34) 918 85 50 60 Fax: (34) 918 85 50 62 -------------------------------------------------------------------------
