Abstract for JLab Technical Note 98-046 

In this note the cryogenic data of the Hall A cryotarget are analysed. We will provide a value of the error on the target density. After having checked the consistency of all the temperature and pressure sensors, and corrected them from their offset, the density error is computed. One finds 0.074% for the hydrogen loop and 0.070% density uncertainty for the deuterium loop. A check of the cernox temperature sensors is also provided showing that one cernox in both loop one and loop two has not the same calibration than the two others. All the calibrations for loop three are consistent.
