• Analysis of the Field Maps (2 July 2015) (Mapping_analysis.pdf)

Summary of the analysis procedure, including probe recalibration, revised contour plots, and E0-independence of the raytracing results.

Additional copies of figures in this note:

• Figure 2 - Probe calibration factors
• Figure 3 - Field boxes and endplanes
• Figure 4 - B vs x and y before recalibration
• Figure 5 - B vs x and y after recalibration
• Figure 6 - Contour plots before recalibration
• Figure 7 - Contour plots after recalibration
• Figure 8 - Error in energy due to using 1.5T map at 6 and 13.6 GeV


• Some Small Effects in Tagger Raytracing (17 July 2015) (Small_effects.pdf)

Details on the effect of probe recalibration and omitting the FOCAL field box

• Interpolation between the field maps (2 July 2015) (E0_interpolation.pdf)

  How to interpolate between the field map raytracing results for E0 = 6, 12 and 13.6 GeV.
  Since the focal plane position as a function of E/E0 varies by less than a microscope channel width, this note is of academic interest only -- the 1.5 Tesla (12 GeV) map should be accurate enough in all cases.

• Measurement of the field maps (20 Feb 2014) (Field_mapping.pdf)

  Presentation to GlueX collaboration meeting of 20-Feb-2014, describing the measurement procedure, consistency checks, and comparison with Tosca calculations.
