The wires were redone and there might be differences in the distances 
between the wires.
Previously one of the wire had become lose. Yesterday one of the wire 
was broken.

Now the distance between the extreme wires is 14 mm.

The scan was aborted after 008 sequence because clouds appeared.

Then sky cleared.

iflat1 to iflat5   ND= .3+ .13 +.04  EXP = 5 sec   
gflat1 to gflat5   ND= .3+ .13 +.04  EXP = 1  sec  
xflat1 to xflat5   ND= .3+ .13 +.04  EXP = 500 ms  

Flats are alright.

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.

Some clouds appeared in between, while I was taking lunch.
