SP-349/396 PIONEER ODYSSEY

Figure 7-4. Typical 24-hour observation chart used to command the imaging photopolarimeter and later used to determine how the instrument operated at the time pictures were taken. It provides a visual check on what is happening at the spacecraft as far as the look angle of the instrument is concerned. (a) Is how the chart looks when the spacecraft is distant from Jupiter. (b) Shows the chart about the time of closest approach. The main features of the chart are described in the accompanying text.
