Continuum Logitudinal Transverse Velocity (6301.5 Å)

Thermal Drift (Level0 -> Level1)

Average Centerline (Level0 -> Level1)

The four solar images of the SP map show, from left to right, continuum intensity, a measure of the longitudinal apparent flux density (Blapp -- like an ordinary magnetogram), the transverse apparent flux density (Btapp), and the Doppler shift of the 630.15 nm line as derived from the wavelength of minimum intensity in the Stokes I profile.

The two lower plots show the measured thermal drift (dots in green) of the thermal drift of the SP image along the direction of the slit (top graph) and in the wavelength direction (bottom graph) as a function of UT in the particular SP operation. The yellow curves are smoothed fits to the measured shifts; these fits are used to adjust the data for the thermal drifts. These displays are used to verify that the analysis proceeded correctly for this operation. The orange symbols indicate the cadence of the observations.

The SOT-SP calibration software is largely the work of Bruce Lites, HAO with major contributions from the instrument team, including Ichimoto san et.al. The maps which are graphically summarized on this page were generated via stksimages_sbsp.pro . All SOT/SP software (level0->level1->level1+) is distributed within the SOT branch of SolarSoft.
SolarSoft clients which do not have access to data locally may incorporate the map data summarized on this page into your current sswidl session via verbatim cut&paste of the the following sswidl command:
IDL> stks=sotsp_stks2struct('20220705_230406')
The above will copy data from the SOT-SP Level2 server; Then, for example
IDL> help,stks,/str
Output structure tags map 1:1 to save file 'Output Parameters' description in doc header of stksimages_sbsp.pro

Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and NSC (Norway).
