#/ Overview #\

Program getpar parses a spool file of the listing of Solve solution, 
extracts information from there, formats it and writes down in the
set of output files. 

#/ Usage #\

  Usage: getpar <spool_file> <prefix>                                 
                                                                      
where 
  spool_file is the name of Solve spool file of global solution in 
                either complete or back mode; 
  prefix     is the main portion of the output filenames including path. 
             The actual names of the output files are results of concatenation 
             of prefix with extension. 

#/ Formats description #\

   Each output file has first two lines comments. The comment lines contains
character # as the first character in the line. The first comment line, 
adn therefore the first line of the file always holds the name of the format,
its version and date of format revision:

# GETPAR_XXX format version 1.0  of 2001.05.25

  where XXX is (in catpital letter) extension of the file, for example,

# GETPAR_STA format version 1.0  of 2001.05.25

  The second line, so-called header comment, contains the full path name of 
the spool file. Since the format of getpar output files is the subject 
of changes it is a good practice to check the format version each time when you 
parse getpar output files.

##/ .sta -file ##\ 

   .sta file contains estimates of positions of global stations and the formal 
uncertainties of these estimates. The list of station positions is sorted in 
alphabetic order of station names. Stations before and after episodic motions 
are treated as different stations. Correlations between station positions and 
velocities are also written. 

   File contains lines of four types:

1) Comment. The first character is #. Header comment contain the full name of 
   the spool file.

2) Cartesian components of the vector of station position. The first 
   8 characters of this line are STA_GCX:

##/ .bas -file ##\ 

   .bas file contains series of the estimates of the components of baseline 
vectors of the stations whose positions were estimated as local parameters
as well as formal uncertainties of these these estimates. The list of the 
estimates of baseline vectors is sorted in the order of sessions and then in 
the alphabetic order of station names forming a baseline. All three component:
baseline length, transversal and and normal components are computed.

   .trp file contains apriori zenith path delay, adjustments of zenith
path delay, totals (apriori+adjustments) and formal uncertainties of 
adjustments for each session, each station. In the case if zenith apriori path
