SDO AIA and HMI Bz, 2010-05 to 2016-12, two times a day, 256 x 256
frames.tar holds frames/<YYYYMMDDTHHMM>.npz (UT), one file per time at 00:00 and 12:00 UT from May 2010 to
December 2016. Each file holds the AIA channels present among aia94, aia131, aia171, aia193, aia211,
aia304, aia335, aia1600 and aia1700 (DN/s) and bz, the line-of-sight component of the HMI vector
magnetic field (gauss), as 256 x 256 float16 arrays.

Changes from SDOML v2
The frame nearest 00:00 and 12:00 UT of each day (within 10 minutes) was taken from each array, averaged in 2 x 2 blocks from 512 x 512 to 256 x 256 (about 9.6 arcsec per pixel; the solar radius is fixed at 976 arcsec, about 101.7 pixels, with the disk centred at pixel 127.5), clipped to the float16 range and stored as float16. Times with no AIA channel were left out; a channel that is missing at a time is absent from that file.
