Lambda2M crashed at `dm_workflow.detectors.getDetectorByNumber()`

@prjemian Please see the error defined. It looks like we are missing some kind of setup/configuration file in spec_support/detector_parameters.py?

@prjemian @sureshnaps Here's the difference when running the same function dm_workflow.detectors.getDetectorByNumber() with the Eiger's detector number and Lambda2M's detector number:

In [4]:

As you concluded in the Teams discussion, the catalog of detectors available for use by SPEC and Bluesky is defined by a Matlab file (detectorinfo.m). This file is read into a Python dictionary: https://github.com/aps-8id-dys/ipython-8idiuser/blob/44c7e4f36042832bb7c93511cbdfb6d35ee847d5/profile_bluesky/startup/spec_support/detector_parameters.py#L44-L45

I believe the beam line's choice is to update this file from Matlab.

[prjemian]

So, when this code: https://github.com/aps-8id-dys/ipython-8idiuser/blob/44c7e4f36042832bb7c93511cbdfb6d35ee847d5/profile_bluesky/startup/instrument/plans/xpcs_acquire.py#L147

calls this code: https://github.com/aps-8id-dys/ipython-8idiuser/blob/44c7e4f36042832bb7c93511cbdfb6d35ee847d5/profile_bluesky/startup/spec_support/detector_parameters.py#L32-L33

it failed to find detector number 27.

Suresh added definition for the detector. Issue fixed.
