There are discrepencies in the y-position of the calibrating crystals in the multiruby example. The results shown below give the orientation and positions of the same grain given in the three files: * [dexela_id3a_20200130.yml](https://github.com/HEXRD/examples/blob/master/NIST_ruby/multiruby_dexelas/include/dexelas_id3a_20200130.yml): monolithic * [dexela_id3a_20200130_distorted.yml](https://github.com/HEXRD/examples/blob/master/NIST_ruby/multiruby_dexelas/include/dexelas_id3a_20200130_distorted.yml): monolithic with distortion function * [dexela_id3a_20200130_comp.yml](https://github.com/HEXRD/examples/blob/master/NIST_ruby/multiruby_dexelas/include/dexelas_id3a_20200130_comp.yml): composite Each file has a section `calibration_crystal`, which contains the fitted orientations and positions of the three crystals in the specimen. Each file has three crystals but the order is not the same in all. Individual crystals can be identified by their orientation, and the orientations are in very close agreement. Likewise, the x- and z-positions are very close, but the y-positions vary by over 100 micrometers. For all three files, the y-position varies across the three cyrstals. In fact, there appears to be a consistent offset. The monolithic with distortion is about 80 um more than the composite, and the monolithic is about 130 more than the composite. ``` crystals: 0, 0, 1 orientation: orientation: orientation: - 1.2148784044413221 - 1.215186719556741 - 1.216154387853489 - 0.6945507909200794 - 0.6951399993864372 - 0.6968723940137541 - 0.765702046701113 - 0.7652899393752023 - 0.7641242011231963 position: position: position: - 0.06060121926310595 - 0.062376192982663094 - 0.06210286714055197 - 0.1312120981443553 - 0.08058718647629351 - -8.824811070374732e-05 - -0.06694059935413639 - -0.06896687021379587 - -0.06802617226264575 ``` The same thing happens with all three cyrstals: ``` crystals: 1, 1, 2 orientation: orientation: orientation: - 1.4105172207115466 - 1.4105340942345905 - 1.4099410088929247 - -0.14336674130145605 - -0.14348059590076465 - -0.14100994607869302 - -0.37238882282338215 - -0.3723038198382216 - -0.3744182154504031 position: position: position: - 0.016940740257706914 - 0.017289820066692933 - 0.01899441270201455 - -0.1183857552099456 - -0.1663676385029688 - -0.24948708702253838 - 0.34767784259162654 - 0.347969622169141 - 0.3506372539196996 ``` and ``` crystals: 2, 2, 0 orientation: orientation: orientation: - 0.34356534660437343 - 0.3435633536849311 - 0.34336499403802 - 0.8170405732053853 - 0.8168778798606029 - 0.8194611392200433 - -0.01649123635877074 - -0.01646827287817391 - -0.01682126887333733 position: position: position: - 0.01052568572502354 - 0.009675714272255552 - 0.002650786849134199 - -0.11080094260256373 - -0.16062921141263217 - -0.2358059585521713 - -0.33689416855383947 - -0.3388488872641141 - -0.34287490726628705 ```
