Standard workflow to produce "Wiener-inspired" filter parameters.

[brettviren]

OSP (and SPNG) utilize the "Wiener-inspired" filter which is a "high frequency" aka "low pass" filter parametrized by a "scale" and a "power" number.

It would be nice to have a "standard" workflow to produce the filter parameters for a given detector.

The procedure is outlined:

• Simulate an isochronous track, perpendicular to the wires of a given plane and drifted long enough to have 1mm diffusion in the drift direction.

• Simulate pure noise using an incoherent noise model for the given detector.

• Form the S/(S+N) ratio as a function of frequency.

• Fit this to the Wiener-inspired model, ensuring it is constrained to be 1.0 at zero frequency.

• collect / identify prior "ad hoc" calculations

• evaluate if any are practical for making general or use for guidance

• develop a workflow (eg with snakemake) and configuration to automate as much as possible. See the "spdir" workflow as an example.

• resulting code goes into WCT proper.
