Hinode SOT-SP Level 2 (vector magnetic field) spectral line inversions

Overview

Description

This is the mirror of Hinode SOT-SP Level-2 data created by HAO.
SOT-SP Level-2 data are the output of a spectral-line inversion scheme.
It contains the vector (three-component) magnetograms and a set of related variables.
They are outputs from spectral line inversions using the HAO “MERLIN” inversion code developed under the Community Spectropolarimetric Analysis Center (CSAC), witch is an HAO/NCAR Strategic Initiative.

Each Level 2 dataset is stored in a FITS file containing 42 extensions, one per inversion parameter or ancillary data product. These FITS files are stored grouped into directories for each commanded SP operation.

The Level 2 FITS extensions are organized as follows:

Extension	Quantity
1	Magnetic field strength
2	Magnetic field inclination angle, in [0°, 180°]
3	Magnetic field azimuth angle, in [0°, 180°]
4	Doppler shift of 6301.5 Å line
5	Doppler shift of 6302.5 Å line
6	Doppler width
7	Line strength
8	Damping parameter
9	Source function
10	Source function gradient
11	Macroturbulence
12	Stray light fraction
13	Stray light shift
14	Magnetic field strength error
