Argast, Farlow (our paleontologist) and spouses. It's a groovy department.
This is a place to find references, archived data, and other information.
wadzip.zip Everyhing that makes the WAD run.
unzip.exe Just what it says -- for OS2.
goserve.zip The web server running this site. Go to the
official goserve web site for more information and the latest
version.
Download xrdptvga if you have a VGA or SVGA monitor. Use xrdptega if you have an EGA Monitor.
These programs were written for in-house use. You will consequently be limited in hard-copy
options (an AMPLOT II connected to LPT1 is the only possibility right now.) You will also need to
store the data on your D: drive in a directory called \data\xrd.
One possibility for getting hardcopy is to download the data, strip the header with a text editor, import the ascii file to a standard plotting program, run a smoothing algorithm and plot it.
The programs were originally compiled in Borland Turbo Basic. I slightly revised the programs for this site and recompiled them in Microsoft Basic 7.1. Feel free to modify the original code to suit your personal needs but do rename it so as not to confuse the originals.
No guarantees (and use the centroid option with care, I'm not sure if it works right.)

line 1. Step size in degrees
line 2. Count time in seconds
line 3. Date the diffraction pattern was made
line 4. Time the diffraction pattern was started
line 5. Sample name
line 6. Tube voltage (kv)
line 7. Tube current (ma)
line 8. Random or Oriented mount
line 9. Misc. Information
line 10. Misc. Information
line 11. Starting angle
line 12. Ending angle
This header is followed by two columns of data containing angle and counts information.
Counts are converted to cps. The data are unsmoothed and must be processed unless a very noisy pattern is desired.
By convention: data files on this site have a .dat extension. Save the file to D:DATA\XRDDTA\filename if you want to read it with one of the plotting programs.
