 The scan data of transit time / gain must be corrected before use, as the coordinates of the beam do not necessarily correspond to the primary spot on the photocathode that is illuminated, since air-glass boundary refracts the beam. 
 
- - As before, we have to simulate the beam used during the scan measurement (see for example `Beam::configureXYZScan_PicoQuantSetup` and `Beam::runBeamPicoQuantSetup` for the beam used in Münster)
- - In in `runXYZfrontalScan()` of `OMSim_efficiency_calibration.cc` change the scan range (`grid` vector) and radius limit (`rLim`) according to the diameter of your PMT
- - Adjust the binning of the output histogram in `OMSimEffiCaliAnalyisis::writeHitPositionHistogram` to a finner binning as before
- - Run the XY grid simulation **using the simple PMT**. 10000 photons per grid position should be enough, but you may increase / decrease statistics as you want
+ - As before, we have to simulate the beam used during the scan measurement. 
+ - Run the XY grid simulation **using the simple PMT**, check the function being used under step 4

  - Follow the analysis in the notebook `documentation/notebooks/scans_matching/` and save the created files in `common/data/PMTs/measurement_matching_data/scans/`.  Note that OMSim expects a naming convention for these files (see `OMSimPMTResponse::configureScansInterpolator`).
  - Modify `getScannedWavelength` of your PMT response class for the wavelengths you scanned and add the `configureScansInterpolator` in the constructor.  
- - Run the simulation in step 5 to check the output with the newly introduced files
