Calibration Data on Film


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1967-07-28 to 1968-12-30


This 16-mm microfilm data set was generated from tape data set 67-073A-12M provided by the principal investigator. It contains calibration data for experiment 67-073A-12 (Reed). Each calibration cycle is contained on six frames. All plots are linear and show, as abscissa, seconds after ascending node. The abscissa scale ranges from 0 to 6000 seconds. All frames contain two graphs, one above the other, and the frame heading shows year, day, and universal start and stop times in milliseconds of day. The first frame in a cycle contains electrometer zero in volts as the ordinate, with the low- and medium-gain outputs (volts) shown in the upper graph, and the high-gain output shown in the lower graph. The next frame shows dark current (volts) as the abscissa in the upper graph and experiment temperature (deg C) as the ordinate in the lower graph. The next four frames have as the ordinate electrometer output minus dark current in volts, with one frame showing mirror position zero in the upper graph and mirror position 1 in the lower graph. The following three frames show the response for mirror positions 2 and 3, 4 and 5, and 6 and 7. The accompanying documentation describes the calibration procedure.
