Extraction Commands used

Using https://github.com/scivision/histutils we created the .h5 HDF5 files.

python ConvertDMC2h5.py ~/data/neo2013-01-13_X38_frames8300-9500.tif -o ~/data/cmos2013-01-14T1-15.h5 -s 2013-01-13T21:14:34Z -r 33.2398849368143 --cmos 480526 481726

python ConvertDMC2h5.py ~/data/2013-01-13T21-00-00.DMCdata -o ~/data/ccd2013-01-14T2-38.h5 -b 4 4 -s 2013-01-13T21:00:00Z -r 36.88675765400221320545 -t 2013-01-14T02:38:00Z 2013-01-14T03:00:00Z

python ConvertDMC2h5.py ~/data/2013-01-13T21-00-00.DMCdata -o ~/data/ccd2013-01-14T1-15.h5 -b 4 4 -s 2013-01-13T21:00:00Z -r 36.88675765400221320545 -t 2013-01-14T01:15:00Z 2013-01-14T01:17:00Z

Likewise for convenience we made a lossy compressed preview video ( > 50:1 compression)

python Playh5.py ~/data/ccd2013-01-14T2-38.h5 -o ~/data/ccd2013-01-14T2-38.ogv -c 1000 4000

python Playh5.py ~/data/cmos2013-01-14T1-15.h5 -o ~/data/cmos2013-01-14T1-15.ogv -c 10 4000

We didn’t make the Ogg Theora (.ogv) compression part of the main conversion program because some systems don’t have the proper compression algorithm installed. Virtually every device/computer will have the ability to playback these OGV videos, however, for example through VLC.
