To persons interested in FORTRAN programs RCN, RCN2, and RCG:
     My atomic-spectra programs have been upgraded to RCN36, RCN236,
and RCG11 by modifying common statements to make a common of given
name the same length in all routines and make the number of integer-
variable words of storage an even number if followed by a floating-
point variable.  Also all quirks of compilers on a CRAY, VAX, SUN, or
IBM System/6000 RISC have been taken into account, except that on the
IBM version 1.0 FORTRAN compiler, backspaces in RCG do not work, so
be certain that you use at least version 2.0 (or maybe 2.02).
The codes also run on Power Macintosh computers, using the Language
Systems Fortran compiler or the Absoft compiler, and on PC
compatibles, using the GNU g77 and similar compilers.
     The three source files (VAX/MAC versions) and various sample
input data files have been placed in a public ftp directory
          ftp/pub/cowan
on the Los Alamos t4 network, and can be accessed via the World Wide Web,
using the URL (Web address)
                        ftp://aphysics.lanl.gov/pub/cowan/
or go to               http://www.t4.lanl.gov
and follow links to my codes.
     For use on other computers, in each of the three programs modify
the timing routine SUBROUTINE SECONDS by commenting out the VAX section
and uncommenting the appropriate section, or add code pertinate to
the computer in question.  If necessary, one may simply set t to 0.0,
as times are for information only.
     The files rcng.UNIX and rcng.VMS are procedure files for use
respectively on UNIX and VMS systems for performing complete
RCN/RCN2/RCG calculations one after the other.  The included RCN input
configurations for a test calculation in K+5 can of course be
replaced, using a suitable editor, for calculations in any other
atomic system.  The files diel.UNIX and diel.VMS are analogous
sample files for making autoionization-rate/dielectronic-recombin-
ation-rate calculations in Se+24.  The other files are mainly sample
input and output data files for the three calculations useable for
debugging purposes.  For a first RCG calculation, use ing11k (renamed
ing11) as input in order to calculate binary files TAPE72, TAPE73, and
TAPE74 for subsequent RCG calculations; this input file contains all cfp
decks that can be used in RCG with the dimensions provided.  The file
CFP includes additional cfp decks (for f5, f6, f7, f8, f9, and f10),
but these can be used in RCG only if numerous dimensions are increased
appropriately, as described by comment cards in the RCG source
program, lines 134 to 152.  [Note: The normal input file names are in36,
in2, and ing11; also, ine20 for a program RCE not described here.]
     Relative computing times on the CRAY, SUN, IBM RISC, and some
Macintosh and PC desk computers are roughly:
                          RCN         RCN2       RCG        RCE
      CRAY(Y-MP):         1.0         1.0        1.0        1.0
      SUN(Sparc2):        15           4          2
      SUN(Sparc20):        4
      SUN Ent. 3500        1           5         0.3        0.2
      IBM930:              4          1.3        0.2
      IBM550:             2.5         0.7        0.2
      IBM320H(32H):        4          1.2        0.3
      MAC 6500/300        2.4         20          4          6
      MAC G3/350          2.8         75          7
      Pow. Cen. Pro 240   3.2         12          6          5
      MAC G4               1           3          2
      IBM Aptiva E275      1          16          2
      SGI Origin 200      0.3         1.7         0.7
 
[The SUN Enterpise 3500 has four 336 MHz processors, the Power
Center Pro MAC clone has a 240 MHz processor, the MAC G4 has two
500 MHz processors, the Aptiva has two 475 MHz processors, and the
Silicon Graphic has four 180 MHz processors.]
     Absolute computing times for three-configuration K VI (K 5+)
runs are on the CRAY about 1.8, 0.03, 0.4, and 0.2 sec for RCN,
RCN2, RCG, and RCE, respectively, the RCE time being for test-run
convergence in three cycles.
 
     If you have no FTP facility, I can try sending the files directly
by e-mail (with RCG divided into three sections).
     If you have no e-mail facility at all, I can write the files on
3 1/2 inch 1.4 Mbyte floppy diskettes in Macintosh format or in DOS
format.

P.S.  There are 30-odd files in the anonymous ftp directory.  (Ignore
the "jmann" and "nils" subdirectories and files therein.)  This includes
also a least-squares level-fitting program RCE not mentioned above.
The three writeups contain only partial sample input and output
--hard-copy writeups including longer sample output with hand-written
explanatory notes are available upon request to the author.
