Level 2 Help for PHOTFIT2M_GENERAL

File names of the input input IBIS photometric catalog files.
There are 18 columns in this file. 
All are not used exept for columns # 11, 12, 13, and 16. 
These columns contain :
	column # 11 = incidence angle (degrees),
	column # 12 = emission angle (degrees),
	column # 13 = phase angle (degrees)
	column # 16 = I/F reflectance values as computed from the photometric 
		      function.
	column # 18 = Class-ID

Photometric function :

This parameter selects the menu point for input the photometry task:
   1. to run the program without using a photometric function, you have 
      to select "NONE"'
   2. to read in the photometric function and its associated parameters
      from a photometric parameter file, you have to select "PAR_FILE" and
   3. to put in the parameter by yourself from the tutor mode, 
      you have to select the desired photometric function.

When returning to the highest level of the menu (i.e. the MDF-file) you will
see that the third selection point has been changed according to your input of
PHO_FUNC in this menu.

The class_id nummerates the photometric functions. For using different fotometric functions or parameter sets.

Causes subroutine Metropolis to renormalize itself by recomputing the
Boltzmann coefficient. NORM=n causes renormalization each n successful
iterations. 

Number of rerun of metropolis.

Specifies the number of successful iterations which Metropolis will
perform before ceasing in it's hunt for the coefficient values.
Usefully is for MAXITER is:
for MINNAERT 5000
for VEVERKA  20000
for HAPKE_* 20000
for HAPKE_* 20000 

Specifies the number of successful iterations which must be 
accumulated before the width of the solution generating  probability
function drops by a factor of ten. If for example MAXITER/NUMTEN
is 4.0 then the initial range specified by the MTEMP or HTEMP...
parameter (the starting temperature) is reduced by 4.0 orders
of magnitude (10000:1) by the time the iteration process has
ceased. 
Default for NUMTEN is: MAXITER/4

The minimum acceptable # of points
with residuals below tolerance.
The percent and tolerance keywords permit a solution that is found to
consist of a subset of all of the data points. If there are more than
percent of the points with I/F residuals below tolerance then the
remainder of the points can be ignored if they exceed tolerance.
If there are fewer than percent points with residuals below
tolerance then all of the points will be considered.

The I/F residual tolerance.
The percent and tolerance keywords permit a solution that is found to
consist of a subset of all of the data points. If there are more than
percent of the points with I/F residuals below tolerance then the
remainder of the points can be ignored if they exceed tolerance.
If there are fewer than percent points with residuals below
tolerance then all of the points will be considered.

!.VARIABLE PLOT
!Keyword for plotting the residuals of the 
!fits on the input tiepoints.
!The default is to plot the residuals.
!NOPLOT deactivates printing of residuals.
!See PRINTRON to select device.

Keyword for printing of the IBIS input files.
NOPRINT deactivates printing of IBIS input file.

!.VARIABLE DISP
!Keyword to plot on image display.
!DISP       : Plot display.
!NODISP     : Without generted graphs.
!WAITNOMORE : All graph images will be save in the PostScript image file.

Causes subroutine Metropolis to list the iteration progress as it
converges upon the solution. METROP=n causes a printout each
n successful iterations.
