Level 2 Help for TIEPARM

INP

Input file name.  This parameter is input as:
     INP=innam
where "innam" is the input file name.


OUT

Output file name. This parameter is input as:
     OUT=outnam
where:
"outnam" is the output file name.


MODE

  TOPARM is the default mode.  In default mode, there is an IBIS interface file
as input and a parameter dataset as output.  

  In  TOIBIS mode there is an input parameter data set specified via the PARMS 
parameter (unless NAH, NAV, and TIEPOINT are specified on the command line.)
There is also an output IBIS interface file.  The IBIS interface file is
specified using the OUT parameter if a new file is to be written.  It is
specified using the INP parameter if an existing file is to be written into.


COLS

The default columns in default (TOPARM) mode are 1,2,3,4.
The default columns in  TOIBIS mode are 1,2,3,4


NCOL

NCOL specifies the number of columns to be contained in a new IBIS interface
file produced in TOIBIS mode.  The default for NCOL is the highest column
number specified for the COLS parameter.  


NAH

The nah is number of grid cells horizontally, the number of tiepoints 
across is one larger (nah+1).  NAH must be an integer.  The default value is 20.


NAV

The nav is number of grid cells vertically, the number of tiepoints
vertically is one larger (nav+1).  NAV must be an integer.  The default value 
is 20.


TIEPOINT

The TIEPOINT keyword and associated numbers specify the mapping of control
points between output and input pictures.  The numbers which follow this
keyword are in groups of 3, 4, or 5, one group for each tiepoint.  The numbers
may be either integer or real.  The total number of tiepoint numbers must
be  3,4,or 5 times the desired number of tiepoints.
The order in which the tiepoints are specified is left to right within
a horizontal row of tiepoints.  The horizontal rows are ordered from top
to bottom.


PARMS

A parameter data set containing the tiepoint parameters.  This file should
have been written by a program which uses the XVP routines for writing
parameter data sets, such as TIECONM.
