(Case 1, if the CLASP-2 slit is almost parallel to the north-south direction) -2 hours ~ -1 hour : 1 context map for QS (obs A) -1 hours ~ start of launch window : 1 context map for plage (obs A) launch window (roughly 1 hour) : repeat high-cadence scans (obs B) end of launch window ~ +1 hour : 1 context map for plage (obs A) +1 hours ~ +2 hour : 1 context map for QS (obs A)
(Case 2, if the CLASP-2 slit has an angle of more than 15 degrees) -2 hours ~ -1 hour : 1 context map for QS (obs A) -1 hours ~ launch window ~ +1 hour : repeat context maps for plage (obs A') +1 hours ~ +2 hour : 1 context map for QS (obs A)
obs A: single scan with fast mode, 320" x 160" (2048 slit positions and 1024 pixel high), 2x2 binning, single side mode for context map
obs A': repeat scans with fast mode, 320" x 160" (2048 slit positions and 1024 pixel high), 2x2 binning, single side mode for context maps
obs B: repeat scans with fast mode, 5" x 164" (32 slit positions and 1024 pixel high), 2x2 binning, ~1 min cadence (2 cycles (1.6 sec) at one slit position), single side mode |
