Detector Geometry
Where to find the latest geometry, and how to optimize it.
The GeomOpt class estimates the detector distance based on the fact that rings in a silver behenate powder should be equidistant. If a powder pattern has been pre-computed -- e.g., by the RunDiagnostics class, one can set the powder argument below to that path. Otherwise, the powder argument should be set to the number of images to use to compute the powder. The following snippet of code uses the latter approach:
from sfx_utils.diagnostics.geom_opt import GeomOpt
geom_opt = GeomOpt(exp='mfxp19619', run=19, det_type='epix10k2M')
geom_opt.opt_distance(powder="powder_max.npy", plot=True)
and yields the following information:
Detector distance inferred from powder rings: 83.94 mm
