Wu Command file: 04.08.20.13:20:10.cmd.log Activity: --------- 1) Flat Field Calibration Study Sequence: 04.08_ffield.tcl, grt = 1 SCI_SPEC: OVI detector flat field around the two planned OVI grating positions. Sit&Stare at ~1.45 Rsun and scan through OVI grating positions from 166000 to 199328, with reference position of 166000. Mirror is fixed at 17075 for ~1.45 Ro, taking into account the pointing offset of +716 and maximum X-talk correction for 199328. Target is a stable coronal hole region of the corona.
