This example data references a set of Spec data files that have been used during testing. These Spec files reference a series of scans. Each point in a scan has an image file associated with it that is contained in a subdirectory images/fileName/SNNN where

  • filePrefix is replaced by the spec file name without the extension
  • SNNN represents the Scan number (i.e. S001, S002, S014, etc)

Each scan directory described above will contain a series of tiff images which represent an image per scan point.  The filename will be be filePrefix_SNNN_XXXXX.tif where

  • filePrefix is again replaced with spec file name without the extension
  • SNNN represents the Scan number (i.e. S001, S002, S014, etc)
  • XXXXX represents the point number in the scan, with leading zeros, with scan numbers starting with zero.

If you need to copy the spec file to another computer, you will need to copy the content of the images subdirectory structure for this data into the same folder.



1.) 3-D RSMs (isosurfaces, plane cuts, etc.). This is a small data set, but probably rather typical of many measurements that we will be doing.

/net/s33dserv/export/33bm/data/emery/20140212/PZT_STO/PZT_STO_1.spec

The following scans sets are three individual peak scans, so they should not be combined all together, but only scans within each scan set.

2.) The biggest stitched together pole figure data set we have taken so far:

/net/s33dserv/export/33bm/data/emery/20140212/MoNandMgO/JK112113P2mSa_1.spec

The three scan sets can be combined to produce one large data set.

DescriptionScansImage
tth = 3322-42
tth = 3843-65
tth = 4366-91
All together22-91

3.) The most beautiful pole figure (though we don't really know what the patterns mean…)

/net/s33dserv/export/33bm/data/emery/20140212/Fe2O3_2/YSZ111_1.spec

Both scan sets are separate pole figures, so should be treated independently. The second one is the more beautiful one…

DescriptionScansImage
Scan 117-44
Scan 2 (Nice features)45-69

4.) Example of a powder diffraction scan. The only thing of interest here is the Q-histogram (Intensity vs. |Q| or 2-theta).

/net/s33dserv/export/33bm/data/schlepuetz/20140212/Lab6_test/Lab6_1.spec

Each of these scans should yield the same powder pattern, but withy differing data quality and statistics.

DescriptionScans
High resolution scan2
Medium resolution scan5
Low resolution scan6

 

5. I put some data we acquired at Sector 13 on the six circle instrument into our dserv data directory:
/net/s33dserv/export/33bm/data/schlepuetz/20131204_13BMC/YSZ110_PLDITO_Fe2O3_fired_1.spc
This should result in one big pole figure (stereographic projection).
