  1. Start the correlator (DFB3):
    • login to pkccc3 as corr/*
    • > sdfb3
  2. Start TCS
    • login to a Sun (sagitta) as observer/
    • > atcsver to get latest version of TCS
    • > tcs to start TCS
    • select Digital Filter Bank (time-binning)
    • select Expert mode
    • configuration file is p617
    • cycletime = 4s

To examine data:

  1. Copy from the correlator computer:
    > scp corr@pkccc3:/data2/SDFB3_2/2008-09-29_hhmm-P617.rpf .
    
  2. Load into the pol format:
    > pload 2008-09-29_hhmm-P617.rpf
    > gcopy 2008-09-29_hhmm-P617 20082008-09-29_0753-P617
    
  3. Look at the data (uncalibrated). This example shows scan number 3.
    > showscan 2008-09-29_hhmm-P617 -s 3
    

showscan asks for:

  • a plot device: the first plot is not useful so give carriage return
  • a channel number, then a plot device
    • Graphics device/type (? to see list, default /NULL): /xs (for a screen plot)
    • Graphics device/type (? to see list, default /NULL): filename.ps/ps (for hard copy)
    • > lwp filename.ps from the unix prompt.
