JOP35 - SUMER

SUMER POP 21 - "Coronal Hole Study" (Red Book 8.1.2.1).

The first phase should be run four times, in phase with the CDS BOUND Study. This phase is designed to identify the hole boundary and any macrospicule or bright point activity etc... The second phase is timed to coincide with the CDS CHSTR Study and contains cooler lines as well as some overlap with the CDS lines for alignment etc...

Slit: 1x300 arcsec
Raster area: 300x300 arcsec - centred on CDS field.

Phase 1 - run simultaneously woth CDS BOUND

0.76 acrsec step - 14 sec integration time - 400 steps. Run 4 times.
Total duration = 380 minutes.
Line selection - band centred on He I 584.334A - 2nd order.

Phase 2 - rum simultaneously with CDS CHSTR

0.76 arcsec steps - 44 sec integration time - 394 steps. Run once.
