Seweral gross features are ispediately obvious. As an indication of decay race at different tives, streak records aay be analyzed as a sum of exponential decays. Although this type of analysis is adaittedly arbitrary and somewhat ambiguous because of experimental uncertain- ties, it may oevertbeless be ingtructive, pointi imilarities and differ- ences at tha two wavelengths. Table 11.4 gives decay constants found in this manner as well as extrapolated intensities at burst tine. Intensicies at small tives, of course, do not actually eroroach extrapolated values for wery short decay times. The decay of intensity versus tine is quali- tativeiy consistent with predictions, slrkov ts derails do not give quantitative agreement. A curve calculated frou LAns-2453° ponochromatic contours is shown on an arbitrary scale for comparison. ~ TABLE 11.%--EXPOKENTIAL ANALYSIS OF TEAK re ae ome) os ee hoheEe tal Siete — 355 2 oo
