The raw telemetry file APID 63 contains instrument parameters such as temperatures and voltages on a second by second basis (see WIRE APID information ).
The following are plots of selected quantities over the first 91 days of the mission since launch. (Day 0.00 is defined here as March 5, 1999 03:00 (UT).) The data shown here range from mission day=7.39 (3/12/99 12:21 UT) to mission day=184.07 (06/04/99 00:26 UT).
Here are some temperature plots: html#1 and (PS) . The vertical axis is in units of degrees Kelvin (except for the Voltage supply plots). The horizontal axis is days from launch.
These plots have an expanded vertical scale: html#2 and (PS) .
