GROUNDPREP(1)

NAME

     groundprep - process raw filtergrams

SYNOPSIS

     groundprep [-qv] [argument= value ...]

DESCRIPTION

     groundprep is an experimental module designed to do  a  cer-
     tain  amount  of  preprocessing  on  MDI  filtergrams  taken
     through the heliostat feed.   The  intent  is  to  find  the
     nearest  complete  set  of  filtergrams to a target velocity
     time, dark-subtract and gain-correct them, locate  the  limb
     and  register  them, rotate them to a common position angle,
     and assess the image quality.  The module is not in  use  or
     present development.

     The -q option prints out the list of required arguments  and
     their  default  or environmental values, then quits.  The -v
     option sets verbose mode, redirecting history from stdout to
     stderr.

OPTIONS

     in=name             input dataset name (no default)

     out=Dataset_Name    output dataset name (no default)

     t_start=time        target starting time (no default)

     t_cadence=time      target time interval (no default)

     t_delta=time        tolerance for difference between  target
                         times and observation times (no default)

     dark=float          dark current value (no default)

                         (several more)

     The module is not currently used or kept up  to  date.   The
     binary  executable  differs  substantially  from the present
     source code.
