Atkins / M. P. Miralles: Lead Scientist ---------- R. Wu: Commander M. Uzzo: Planner Command file: Activity: --------- 1) Flat Field Calibration Study with reduced OVI MCP Voltage Sequence: 01.07_ffieldMCP.tcl SCI_SPEC: OVI detector flat field around the Lyman Alpha line position at grtpos 168208 (pixel# 897). Sit&Stare at 1.5 Rsun and scan through OVI grating positions from 165448 to 178596, with reference position of 172000. Mirror is fixed at the crosstalk position for 168204 for 1.5 Ro --> Mirror X-Talk: choose x-talk at 168204, central position, because this gives an error of +- 13 engineering units (about .004 solar radii), and saves lots of bytes and possible errors. OVI Micro Channel Plate Voltage reduced to 205 Engineering Units for the duration of this observation.
