@# This data file contains measurements of the currents on the front ends
# of the two channeltrons of the Cavendish Mott polarimeter, used as Faraday
# cups, with the input to the polarimeter being the reflected beam from a
# magnetic sample, on 12th December, 2001.  The data consist of:
# Column 1: Magnetization direction
# Column 2: Channeltron number
# Column 3: Incident beam energy (eV)
# Column 4: Standard deviation uncertainty in incident beam energy (eV)
# Column 5: Incident beam current (nA)
# Column 6: Standard deviation uncertainty in incident beam current (nA)
# Column 7: Nature of uncertainty in channeltron front end current
# (G Gaussian, T top-hat, P Poisson)
# Column 8: Channeltron front end current (fA)
# Column 9: Standard deviation uncertainty in channeltron front end current
# (fA)
