Hinotori is the 7th Japanese scientific satellite launched in February 1981 into a low-inclination (31.3 deg.), circular (600 km) orbit. The Hinotori Soft X-ray Spectrometer (SOX) observed highly ionized iron emission lines emerging from solar flare plasmas during the period of February 23, 1981 to June 19, 1982 around the 22nd solar activity maximum. More information about the Hinotori Mission and  the scientific achievements of the SOX instrument can be found in the references below.

Original binary telemetry data (SIRIUS files) are archived, and converted into FITS format. Programs to read FITS telemetry data are provided in C and IDL languages:

C:	Read SIRIUS（Frame format）files and convert them into FITS files.
IDL:	Read FITS files and extract the SOX related data sets to save in IDL
 	STRUCTUREs (TSOX).
IDL: 	Read TSOX-STRUCTUREs and create SOX raw spectral data (satellite spin
 	phase vs count rate) with help of Hinotori S/C attitude data, and save
 	in IDL STRUCTUREs (DSOX; Level0*).
IDL: 	Apply calibrations (RSOX; Level1*) and provide routines to derive
	physical parameters for solar flares (Level2*) via CHIANTI† ver. 9.

*SOX data base levels

Level0: time series of SOX spectra (satellite spin phase vs count rate) with SOX-related satellite house-keeping data (e.g. spin period, sun angle, etc.)

Level1: time series of SOX spectra (wavelengths vs intensity [photons cm^-2 sec^-1])

Level2: database of SOX spectra with added physical quantities (e.g. intensity of lines, electron temperature, emission measures, etc.)

†atomic database: CHIANTI　- http://www.chiantidatabase.org/
CHIANTI consists of a critically evaluated set of atomic data, that together with a set of user-friendly Interactive Data Language (IDL) and Python programs can provide diagnostic information from observed emission line spectra of astrophysical plasmasf. CHIANTI is a collaborative project involving the Naval Research Laboratory (Washington DC, USA), the Arcetri Observatory (Firenze, Italy), and the Cambridge University (United Kingdom).
