Scan 10 Region = West limb + 100 arcsec PA = 296 FOV = From 100- 200 arcsec Image rotator = 26 degree Step size = 4 arcsec No. of steps = 26 EXP = 80 s for XI line exp = 60 sec 6374 line Inversion = No Scan started from the limb Start at 14 23 JST Files are r7_*** , xi7_*** 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
