... Proposing for VLBI Time at Arecibo . ... Documentation (Field System, VLBA4 terminal, Mark 5 system) . ... In 2001, the Arecibo Observatory received its hybrid VLBA-MARK IV (VLBA4) data acquisition system, and currently NAIC commits Arecibo to support VLBI observing up to a maximum of 4% of the 305-m's observing time. ... Tracking Time (h:mm) . ... The inclusion of the 305-m Arecibo radio telescope can dramatically boost the sensitivity of VLBI observations, even with its limited source tracking...

... April 14, 2014 . ... It writes VEX files that describe the details of an observation and are becoming the near universal format for distribution of schedules to VLBI telescopes and correlators. This manual describes how to use the program, provides extensive information on all possible inputs, and gives considerable information and advice on many aspects of scheduling VLBI observations. ... This edition of the manual corresponds to the SCHED version as indicated in the title. ... Setup Files . ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... The Wide Field Planetary Camera 2 (WFPC2) is now a mature and largely well-characterized instrument. Information already available through the WFPC2 Instrument Handbook and the HST Data Handbook is fairly complete. In this update we provide additional information obtained from recent studies of the instrument, as well as calibration plans for the WFPC2 and a short note on present and planned imaging capabilities for HST. ... Calibration: Calibration of WFPC2 continues. ...
