What problems are present in the exposure map, or in the times?

(7/15/91)


Currently, there is a data drop-out problem, in that there are times for which no data are present, yet the processing software does not recognize these times. Hence, the 'good time interval' time is not accurate. The effect is that no flux is trustworthy better than about 5 to 10 percent. See question #9 .
