In the analysis of your data would you please check for any baseline errors especially on these antennas and let the Data Analysts (email - analysts@nrao.edu) know what you find when there are significant baseline errors. Thank you in advance. 03Jan16 06:03:40 VX and VA modes begin, VLBA tape rolling. 03Jan16 06:03:40 - 03Jan16 12:29:09 Form #: C110590 # of Ants: 1.00 Downtime: 385.48 Antenna(s) 28 - FRONT END (Front end) Problem(s); Antenna is not fringing - High CAL readings, low SYS/CAL.
