2.2.2 spase://VSPO/NumericalData/Yohkoh/SXT/PT2M Yohkoh SXT multi-level digital data 2012-04-11T10:42:32 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.
