LASCO MVI FORMATThe disk movie format used by LASCO has been designated as an MVI format. 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.
File Header:
Number of columns in each image Number of rows in each image Maximum number of images in file Number of bytes in image header Version number
Extensions for Version 1 and 2:
Image Headers:
