Initial Fits
These fits are listed dose (from Landauer) vs measured dose (from OSL reader).
Calculated Dose vs PMT Counts
These fits were created using OSLs I irradiated using the 20Ci Source. I calculated the dose the OSLs should have on them using the dose calculations on the previous page. The PMT counts came straight from the OSL reader.
Number of degrees of freedom is data points - fit parameters
I should note that the low dose calibration factor from the OSL reader is 9.496494 and 0.6806084 for the high dose. These values are close to the slopes of their respective linear fits.
