NAME

     upsum  - module to do upsum Frequency Determination Panel

SYNOPSIS

     upsum [ -Nntap ] [ -rsnrst ] [ -renred  ]  [  -f1freq1  ]  [
     -fmaxmaxfreq ]

DESCRIPTION

     upsum is a  c-shell script which utilizes several  USP  rou-
     tines  to  construct a upsum panel of the input dataset.  It
     is recommended that a single record at a time be  processed.
     The output consists of the input record followed by a set of
     bandpass  records  corresponding  to  the  number  of  input
     filters  used,  followed by a set of summation records.  The
     upper frequency of each bandpass and upsum  record  is  con-
     tained  in  the  RecNum trace header entry for plotting with
     TPLTR. The first bandpass has the following filter points:

      f1 =  -f1
      f2 =  -f1  + 5
      f3 =  -f1  + 10
      f4 =  -f1  + 15

     The number of output bandpass filters is a function  of  the
     -fmax  and  the  above  bandpass will have each entry incre-
     mented by 10 hertz until the f4 entry becomes  greater  than
     -fmax.

     upsum gets both its data and  its  parameters  from  command
     line  arguments.   These  arguments specify the input, start
     and end records, initial f1 frequency and  maximum  f4  fre-
     quency.

  Command line arguments
     -N ntap [no default]
          Enter the input data set name or file immediately after
          typing  -N  This input file should include the complete
          path name if the file resides in a different directory.
          Example  -N/b/vsp/dummy  tells  the program to look for
          file 'dummy' in directory '/b/vsp'.

     -rs nrst
          Enter start record number.  Default value is the  first
          record.

     -re nred
          Enter end record number.  Default value is last record.

     -f1 freq1
          Enter the initial f1 frequency.  Default value is zero.


     -fmax maxfreq
          Enter the limiting f4 frequency for the panel.  Default
          value is 95 hertz.

program terminates after the help screen is printed.
