This is the Hinode Solar Optical Telescope (SOT) Level-0 data.
The SOT includes the Filtergraph (FG) and Spectro-polarimeter (SP), along with the Correlation Tracker (CT) for image stabilization.
This dataset contains observation data by Filtergraph (FG) and Spectro-polarimeter (SP).

SOT-FG Level-0 data

This is the uncalibrated intensity and polarization data taken by the filtergraph, after having been reformatted from the raw bitstream. The unit of the file is one image with two- or three-dimension.

These data are stored in each observation date directory, like yyyy/mo/dd/<DataCode>/Hhh00/<FilePrefix>yyyymodd_hhmmss.s.fits.

• yyyy : Year, mo : Month, dd : Day, hh : Hour, mm : Minutes, ss.s : Seconds
• H is character “H”, and 00 is charactor “00”
• <DataCode> and <FilePrefix> are strings that identifies the mode of observation, listed on this page.

SOT-SP Level-0 data

This is the reformatted “raw” 4D data (spectral x spatial x 2 CCDSIDES x 4 Stokes parameters). The unit of the file is one slit position, not one raster.
These data are stored in each observation date directory, like yyyy/mo/dd/<DataCode>/Hhh00/<DataCode>yyyymodd_hhmmss.s.fits.

• yyyy : Year, mo : Month, dd : Day, hh : Hour, mm : Minutes, ss.s : Seconds
• H is character “H”, and 00 is charactor “00”
• <DataCode> is SP4D

Supplemental products

The following products are also available:

• SOT Preliminary data (FITS format), temporary data until create Level-0 data
• SOT-SP MAP files (FITS format) using one raster of SOT-SP Level-0 data, created by DARTS
• Quick look images of SOT-FG Level-0 data (PNG format) created by DARTS
• Quick look images of the SOT-SP MAP files (PNG format) created by DARTS

These supplemental products are only for quick reference.

Data search

HNODE Data Center on DARTS

• for SOT-FG
• for SOT-SP

About SOT-SP, this system searches for the MAP files, and output the path of Level-0 data files in a script to download data.

Data Analysis

Hinode data are freely available over the internet and each instrument team provides software written in IDL that is distributed through SolarSoftWare(SSW).
