Description

Create MuonDeadtimeCorrection algorithm which takes as input muon calibration run (workspace) and output a table where the first column should be spectrum number and second column the deadtime correction number.

Just a comment that wiki been updated following feedback from Steve/Adi

Steve etc have an experiment next where if pos would like use this alg.

Steve writes:

Thanks for the updated Wiki pages. Previously when we've tested the new TDC we ran one of the new cards in parallel with the old DAE. Therefore the runs generated have 112 histograms, 1-96 from the old TDC cards and 97-112 from the new. For the tests planned later this week we may have two full DAEs, with histograms 1-96 coming from the old and 97-192 from the new. To enable us to load these runs I've generated two new definition files for EMU (attached). An example run from our previous TDC tests is also attached. This seems to load fine using the muon interface if I replace the EMU 96 detector definition with that for 112.

In addition:

For EMU00019023, which contains 112 spectra, the expected deadtime for spectrum 97 is 8.062 nano-seconds.

Attached is the one-off EMU_Definition file required to load this 112 spectra EMU dataset.

Tried EMU and MUSR and got sensible results.

Tried a workspace from a non-muon instrument and it just failed to fit which appears sensible.
