XRT observation timeline

Orbit events for 21-Aug-2017, 15-20UT (data provided on 2017/08/03).

XOBs

Hinode eclipses Ep. 1:
Hinode eclipses Ep. 3 and 4:
HOP 339 (full-Sun): Regular synoptics and HOP 340 images will serve for this purpose.

HOP 339 (polar-limb):

Data volume estimation

Estimation by COT simulator

Total data volume (15:00 -- 21:20 UT): 2482 Mbits
Rough estimate of total vol. for entire 3 days timeline : 5000 to 5600 Mbits.

Test runs on 8/10

Test run was performed on 10-Aug., 15 to 20 UT (no test for the part after 20UT). Prepared XOBs were run at the same timing, same order. Note that we don't observe flares during the eclipse observations (XRT_FLD_DIS, XRT_FLD_CTL_DIS were set in each sequence).
