Sequential magnetic fit: Co₂SiO₄, D20 scan from 2.3 K

The same staged fit as the Python tutorial, on the command line. The command line fits whatever the project marks free with () after a value, so each stage marks its parameters in the project's files with a text editor and runs edi fit, which writes the fitted values back into the project for the next stage.

Get the project

edi download-data pd-neut-cwl_cosio-d20_scan-213f
python -m edi download-data pd-neut-cwl_cosio-d20_scan-213f

Start with nothing free

The project marks what its finished fit frees. Remove every (), so the stages below free one group at a time.

In experiments/d20.edi, remove the () from every value; they now read:

_instrument.calib_twotheta_offset 0.29433
_peak.broad_gauss_u 0.273527
_peak.broad_gauss_v -0.589718
_peak.broad_gauss_w 0.413007
1 6 603.5
2 6.5 585

The same for every other row (15 more).

In structures/cosio.edi, remove the () from every value; they now read:

_cell.length_a 10.3081
_cell.length_b 6.00219
_cell.length_c 4.78739
Co1 Co 0 0 0 a 4 1 0.269 Biso
Co2 Co 0.2809 0.25 0.9836 c 4 1 0.269 Biso

The same for every other row (6 more).

Scale, 2θ zero and cell

Switch the fitting mode to a single fit, so the stages fit the template alone.

In analysis/analysis.edi, set:

_fitting_mode.type single

In experiments/d20.edi, add () after the values the stage frees:

_instrument.calib_twotheta_offset 0.29433()
cosio 1.81723() 1.0

In structures/cosio.edi, add () after the values the stage frees:

Displacements

Co2's displacement follows Co1's by the project's constraint.

In structures/cosio.edi, add () after the values the stage frees:

Co1 Co 0 0 0 a 4 1 0.269() Biso
Si Si 0.0925() 0.25 0.4283() c 4 1 0.466() Biso

The same for every other row (3 more).

Fit the scan

Back to the sequential mode: every pattern is fitted in turn, each from the fit before it.
