EXPLANATION

First column: .avi or .mov format.
Second column: .mov or .avi format.

Order: by date.
The first movie below is a brief blinker for download and player tests.

Click on image to open movie.
You may have to wait long for the download while seeing only the QuickTime logo.
Click again or switch to the other column if the QuickTime logo has a question mark.
If both columns fail, download directly from the movies directory under (Google) "DOT showpieces".

Get a copy: right-click on movie, "save as source"; or use the browser "save as" option under "file".
A recipe to get multiple or all movies directly from the directory is given under (Google) "DOT showpieces".

Scale: sometimes an Earth insert shows the scale. Centered clocks in four-panel movies usually are Earth size (17.5 arcseconds at 1 AU). A granule is typically about 1 arcsecond (720 km).

Display: most movies are 2x2 binned to fit XGA (1024x768) pixels.

Playing speed: generally 10 frames per second to accommodate most players without frame loss. The speedup is usually about 300 (5 minutes per second). Blink movies run at 1 fps. DOTlogo-small2.jpg

FILE NAME CONVENTIONS

Targets: AR = active region; NW = network; QS = quiet sun; mu = viewing angle; Venus = transit.

Wavelengths: wl = white light; bc = blue continuum near G-band; rc = red continuum near Halpha.
gb = G-band (4305 Angstrom, CH lines).
ca = CaII H core; cac = CaII H core; caw = CaII H blue wing,
ha = Halpha; hac = Halpha line center; haw = Halpha wing (blue+red); habw = Halpha blue wing.
had = Halpha Doppler (blue-red)/(blue+red), dark implies upward, bright downward motion.
171 = Fe IX+X 171 Angstrom from TRACE.
The continua and the G band sample the photosphere, CaII H the low chromosphere, Halpha the high chromosphere.
More explanation on the DOT website (Google "DOT specials").

Fourier filtering: L7 = subsonic low-pass cone below Lamb line 7 km/s.
H7 = supersonic high-pass cone above k-omega Lamb line 7 km/s.
