First Step for Data Analysis of HINOTORI Soft X-ray Spectrometer (SOX) through IDL Routines

Hinotori is the first Japanese solar mission launched in 1981, and the instrument called Soft X-ray Spectrometer (SOX) on board the spinning satellite observed highly ionized iron emission lines emerging from solar flares which occurred during the 22nd solar activity maximum. This paper describes the first step of the project to analyze these SOX flare data through an IDL based system, such as SolarSoft. The telemetried data files of Hinotori were converted to FITS files, and they are now available at the Science Satellite Operation and Data Archive Unit (C-SODA), ISAS/JAXA. Reading these FITS files, time series of data requisite for the following SOX scientific analysis are extracted, and X-ray count data of the SOX spectrometer are divided into raw soft X-ray spectra (counts vs satellite spin phase), which are considered as Level0 data sets used for further analysis.
