mdi.hr_V_bin2x2

Description

Doppler velocity from 30-second observations in high-resolution mode, sampled at second 30 and binned 2*2 on the camera. The data are acquired occasionally during certain targeted campaigns. Some of the data are acquired in linear polarization and some in combinations of circular polarizations; they are distinguished by the value of the key POLSTATE.

Coverage / Duty Cycle

The fraction of possible time intervals containing partial or complete images during each mission phase is as follows:

Special Notes

DP 4a454800 was always acquired in conjunction with one of DP 4b452000, 4b462000, or DP 4a454800 (mdi.hr_M_bin2x2), or with DP 44484800 (mdi.hr_Ld_bin2x2), but not both. To be confirmed!
