Shadow came on the Guider and thus later spectra were saturated as 
sun came out the occulter

xdark1          exp = 1 sec
xdark10         exp = 10 sec
xdark30         exp = 30 sec

rdark1          exp = 1 sec
rdark10         exp = 10 sec
rdark30         exp = 30 sec

Respective darks were taken.

NOTE:Occultor and solar image were focussed for the Red 6374 line only.
   Also occultor was set such that it did not cover the chromosphere.
  One is able to start the spectra from couple of arcsec from the limb
