Files are   ir1_*** , xi1_*** , g1_***

NOTE:  The cloth on CCD camera cast shadow in green line image. 
It was corrected after about 20 spectra

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.
