Solar Orbiter, SoloHI MVI files

SoloHI data cube files in IDL/SolarSoft MVI formats. A single file contains all the information necessary to display the time-lapsed movie. It has been written in IDL and is intended to be played by an IDL procedure. The file consists of three areas, a file header, a series of image headers, and then the byte scaled image arrays. All of the images have the same dimensions.

Solar Orbiter is a mission of international cooperation between the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA), operated by ESA. The Solar Orbiter Heliospheric Imager (SoloHI) instrument was designed, built, and is now operated by the US Naval Research Laboratory with the support of the NASA Heliophysics Division, Solar Orbiter Collaboration Office under DPR NNG09EK11I. The NRL effort was also supported by the Office of Naval Research. Solar Orbiter has an open data policy. The appropriate journal reference to use for SoloHI data is Howard, R. et al.

The telescopic field-of-view is 40 degrees square, boresighted 25.124 degrees off the Sun center, with an angular range of approximately 5 - 45 degrees from Sun center (5.25 - 47.25 solar radii at 0.28 AU). The focal plane array is 3968 x 3968 pixels, giving full angular resolution of 36.7 arcsec. Each image file is a separate readout of the four tiled mosaic detector.
