110720 STONE: A Program for Resolving Mossbauer Spectra Version: July 1984 Author: A.J. Stone, K.M. Parkin and M.D. Dyar Submitted by: M. Darby Dyar, Massachusetts Institute of Technology, Cambridge, MA Operating System: MINC V1.2, RT-11 V4.0 Source Language: FORTRAN IV Memory Required: 40KB Hardware Required: (Two) RX02 floppy disk ports or storage greater than 1600 blocks Keywords: MINC/RT-11 Software, Scientific Applications, Statistics Abstract: This program is an overlaid, condensed version of the larger program MOSSPEC, which is in use worldwide. It fits a sum of Lorentzian or Lorentzian/Gaussian combined lines to a given Mossbauer spectrum by means of the Gauss non-linear regression procedure with a facility for constraining any set of parameters or linear combination of parameters. Results are output as a table of the fitted parameters, including the statistical values for standard deviation, x2, and Misfit. This program was developed to enable sophisticated Mossbauer curve-fitting to be done on a very small computer, such as would be present in a laboratory environment. Use of the detailed User's Manual is strongly recommended. Notes: Use of the accompanying manual is strongly recommended. Restrictions: Program requires approximately 900 blocks of free space for swapping on and off the disk; therefore it can only be run off RX02 (double density) floppies: one floppy for the operating system +STONE.SAV and one floppy for the few .TMP files and the empty blocks (contiguous). This program can also be run off any storage medium with a total of 1600 blocks. Documentation available in hardcopy only. Media (Service Charge Code): User's Manual (EA), One RX01 Diskette (KA) Format: RT-11, 600' Magnetic Tape (MA) Format: RT-11
