Last couple of spectra got effected as the shadow fell on guider

rwire             ND 03   Exp= 1 s  ; Part of lens blocked by shadow
xwire             ND 03   exp =1 s  ; Part of lens blocked by shadow
rdisk2             ND 03   Exp= 1 s  ; Part of lens blocked by shadow

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
