This data product consists of daily sets of four
images created from SOLIS Vector Spectromagnetograph (VSM) data:
(a) photospheric longitudinal magnetic field, based on FeI 630.15
and 630.25 nm lines; (b) photospheric vector magnetic field, based
on FeI 630.15 and 630.25 nm lines; (c) chromospheric equivalent
widths based on the HeI 1083.0 nm line; (d) lower chromosphere
longitudinal magnetic field based on the CaII 854.2 nm lines.
Some recent data are "quick look" while most data are based on
Milne-Eddington inversions. The data are available as both JPEG
images for browsing and as FITS files for quantitative work.
