Title: ANALYSES OF LAUE INTENSITY DATA - INTANAL
 
1. IDENTIFICATION_
 
          Program Name      :  INTANAL
 
          Program Language  :  FORTRAN 77
 
          Authorship        :  John Campbell, August 1987
 
2.   ABSTRACT_
 
     The program INTANAL will read integrated intensity data either from  a
.GE1 file or from  an  AFSCALE  output  file  and  print  analyses  of  the
intensities  as  functions  of  wavelength  versus  intensity,  sig(I)  and
resolution. For data from the .GE1 files  single  films  and/or  ranges  of
films may be selected for analysis.
 
3. PROGRAM_INTERFACE
 
   Input_Files
 
        Unit 5  DATA     Control data file (or input from the  VDU  if  the
                         program is being run interactively).
 
        Unit 1  LAUEHKL  Either the input .GE1 file (direct access) or  the
                         input AFSCALE output file (sequential)
 
   Output_Files
 
        Unit 6  PRINTER  Line printer output (or output to VDU  if  program
                         is being run interactively).
 
4. PROGRAM_STRUCTURE
 
The program determines by calling the subroutine CCPONL whether it is being
run interactively or not and hence whether or not to output  prompts  prior
to reading in each control data card. The program then reads in the control
data. The program opens  the  input  intensities  data  file  of  the  type
requested. For data from a .GE1 file, the program makes a pass through  the
file for each film or range of films requested and collects  the  data  for
the statistics. For an AFSCALE output  file  of  intensities,  the  program
makes a single pass collecting the data for the statistics. The statistical
tables are printed at the end of each pass required.
 
5. DATA_FORMATS
 
The main arrays used for collecting the statistical  data  are  dimensioned
using values defined in parameter statements.
 
6. BUILDING_THE_PROGRAM
 
The program is built from the following modules:

The main source file intanal.for 
 
CCPLIB library routines (CCP4 libraries)
