Yang, I saw you recently posted an update to your tagger design document. It points to the need for an empirical field map. That might be relatively simple to do if only a few points are required, but sampling over an entire grid might be expensive in time and manpower. I wonder if you might give some thought to a comprehensive calibration plan for the tagger and pair spectrometer. They are coupled devices, so the calibration plan should include them both. Maybe we should make it a goal over the next 6 months to publish a note detailing how we envision this to be done. If we need resources to complete it, we better know that now. Richard Jones
