keyword=EPR Calibration for Transvserse Pumping

I did the EPR calibration for the transverse pumping with both pumping
directions on Rb and K. The results are the following:

== Test Condition ==
Cell: Dominic
Oven Temperature: 230C
Field Direction: Transverse -
Laser Power: 3x25 COMET
Cell Density: 7.830 amg

== EPR of Rb ==
Pumping Direction: Anti-Parallel
Data directory: C:\AyeD\EPR\Data\EPR_AFP_20090429_1015
Calibration Constant: 2.210 %/mV
Polarization: 41.35%
Field: 24.71 G
EPR Frequency Shift: 43.29 kHz

== EPR of K ==
Pumping Direction: Anti-Parallel
Data directory: C:\AyeD\EPR\Data\EPR_AFP_20090429_1024
Calibration Constant: 2.202 %/mV
Polarization: 41.26%
Field: 24.72 G
EPR Frequency Shift: 73.28 kHz

== EPR of Rb ==
Pumping Direction: Parallel
Data directory: C:\AyeD\EPR\Data\EPR_AFP_20090429_1037
Calibration Constant: 2.197 %/mV
Polarization: 38.66%
Field: 24.74 G
EPR Frequency Shift: 37.52 kHz

== EPR of K ==
Pumping Direction: Parallel
Data directory: C:\AyeD\EPR\Data\EPR_AFP_20090429_1050
Calibration Constant: 2.208 %/mV
Polarization: 38.10%
Field: 24.73 G
EPR Frequency Shift: 43.24 kHz

Now all the results seem consistent to each other! What's going on in
Vertical?!
