      <Description>There are several data products from the 
Yohkoh Soft X-ray Telescope (SXT) that are accessible through 
the Yohkoh Legacy Archive (YLA) at Montana State University.  
Digital data include Level 0 data, Level 1 Full Frame (whole 
disk) Images (FFI) and Partial Frame Images (PFI) in both FITS 
and XDA formats, Level 2 SXT Scientific Composites (SSC - 
whole disk images) in FITS and XDA, plus corresponding arrays 
of uncertainties due to statistics and decompression, and 
Level 3 images in FITS and XDA.  XDA is a Yohkoh-specific 
standard format under Solar-Soft.  L1 and L2 data are fully 
corrected and calibrated; time spacing between FFI images is 
about 128 sec or longer.  L3 images are optimized for viewing 
as a movie rather than quantitative analysis.  Display data 
include one movie-quality image perday, taken near mid-day, 
and weekly movies built from 12 images per day.</Description>
