YLA provides SXT data in two formats. One is the XDA(SDA) format, which is the Yohkoh-standard format under the SolarSoft environment, and created on a 1 file per day basis. The other is the FITS format, which allows process with more general softwares for analyzing astrophysical data. In our archive FITS files are provided on a 1 file per image basis. These two types of files are distributed from separate search pages.

• Search for files on a daily basis.
  This service access to the following archives:
  
  • Level_2 SXT Scientific Composites(SSCs) in XDA format.
  • Level_2 SSC uncertainty arrays in XDA format.
  • Level_1 Full Frame Images(FFIs) in XDA format.
  • Level_1 Partial Frame Images(PFIs) in XDA format.
  • Level_1 PFIs in FITS format (gzip-ed tarballs for 1 day).

• Search for FITS files (except PFIs).
  This service access to the following archives:
  
  • Level_3 Browse images (for movie) in FITS format.
  • Level_2 SXT Scientific Composites(SSCs) in FITS format.
  • Level_2 SSC uncertain arrays in FITS format.
  • Level_1 Full Frame Images(FFIs) in FITS format.
  Currently, PFIs in FITS format are provided as daily tarballs, i.e. a series of FITS files of the same day are tar-ed, gzip-ed, and distributed from the above search for daily files.
