NAME
     chart  -  a virtual strip chart recorder for continuum meas-
     urements


SYNOPSIS
     $SMALOCAL/bin/chart antenna_number


DESCRIPTION
     "chart" is a  Labwindows-CVI  application  that  provides  a
     facility  to  visualize and record total-power continuum and
     synchronous detection scans.

     The default sampling rate is 1 second, which can be  changed
     on  the  GUI,  under  Save->Sample Rate. On selecting "Start
     Save" option, the user can specify the file  name  and  path
     for  storing  the  acquired  data in an ascii file. The data
     consists  of  6  columns:  time_stamp,  azimuth,  elevation,
     azoff,  eloff, detector output in volts. The time_stamp con-
     sists of date and local time derived the system clock on the
     Sun. The continuum detector output in volts, is displayed on
     the panel along with the date and time.

     The command-line argument  "antenna_number"  is  an  integer
     between  1  and  8,  selecting  the  antenna involved in the
     single-dish work.


OPTIONS
           None.



KNOWN BUGS
     Sampling rates faster than 1 Hz,  are  not  allowed  in  the
     present version.


ENVIRONMENT
     Since the program uses the CVI run-time engine, the  follow-
     ing  paths  should  be  included in the path of executables.
     /opt/cvi and /opt/cvi/bin.
