# Initial Fits

These fits are listed dose (from Landauer) vs measured dose (from OSL reader).

This fit was calculated using only the OSLs provided by Landauer for calibrating the OSL reader.
This fit was calculated using the OSLs provided by Landauer and 6 Nanodot OSLs dosed by using the 137Cs source.

# Calculated Dose vs PMT Counts

These fits were created using OSLs I irradiated using the 9.3Ci 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 = 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.
