High Clouds appeared after 004 spectral sequence.

iflat1 to iflat5   ND= .3+ .13 +.04  EXP = 5 sec   
gflat1 to gflat5   ND= .3+ .13 +.04  EXP = 1.5  sec  
xflat1 to xflat5   ND= .3+ .13 +.04  EXP = 500 ms  

gflats  were taken by moving grating by small amounts 
for each flat. The absorption line effect is expected to reduce
by this way. Falling at different portions of the CCD camera.
