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.

The image started drifting towards south around 4 pm by large amount
even when the guide was not in choice. only in the telescope mode.
The flats were taken keeping the image in north to begin.
