Times listed in this section and on the Oxford data site are in UTC.  Note that unit history logs and data files recorded on computers at JPL are in PST, which is 8 hours earlier than UTC.  Radiometric calibration data was taken at three different instrument temperatures.  At an instrument temperature of 10 $^\circ$C 10\degree{}C  the variable blackbody temperature varied from about 20 K to 410 K. At instrument temperatures of 35 and 60 $^\circ$C 60\degree{}C  the variable blackbody temperature varied from about 90 to 300 K. Each of these tests is described below.  The following types of data files are available for all radiometric tests.  \begin{enumerate}  \item All data from the Diviner instrument is on the Oxford data site at https://www-plan.atm.ox.ac.uk/intra/lro/data/. \href{https://www-plan.atm.ox.ac.uk/intra/lro/data/}{https://www-plan.atm.ox.ac.uk/intra/lro/data/}.  Times in UTC. \item Data from the Environmental Test Lab computer with thermocouple temperatures for chamber components. Times are in PST.  \item Data Logger files with voltages, and currents, spacecraft-monitored thermistors. Times are in PST  \item Files of the Lake Shore diode temperatures (converted from voltage to temperature using Lake Shore curve 10 – this data needs to be converted using calibration curves for individual sensors). Times are in PST.
