DOC how to align to slit edge scan #138

Open prjemian opened 1 year ago

prjemian commented 1 year ago

Need a notebook showing how to align to a slit blade scan where the edge of a slit blade (un)blocks a beam.

The intensity profile is a sigmoidal. The derivative of intensity with respect to slit blade position is a peak. Align either to center or centroid of this derivative.

Derivative might involve use of the ophyd DerivedSignal.

Not so fast, the DerivedSignal looks like it is related to a single Signal source. This issue needs at least two signal sources.
