The length of vertical bar in this figure is equal to twice the standard deviation u 
and has a maximum value of only about 1.4K. This standard deviation amounts to T 
less than 0.1% of the calibration lamp temperature. If the variation in the di 
calibration lamp temperature is indeed responsible for the changes in the active wi 
calibration counts then Fig.l shows that there have been some drastic changes in id 
the temperature of the calibration lamp from time to time. Therefore, the exact 
values of the standard radiances are not known ánd hence the inflight calibration 
constants cannot be computed accurately without further investigation. The use 
of such inaccurate inflight calibration constants will naturally introduce 
errors which could prove to be serious. Instead of using the inflight calibrat- 
ion constants if one uses the preflight values then one assumes that the quality
