        "Description": "The SOLIS Vector Spectromagnetograph (VSM) is an f/6.6\nRitchey-Chretien telescope having a 50-cm aperture.  VSM uses 256 by 1024 pixel\n300 frames/s CCD cameras and ferroelectric polarization modulators.  VSM measures\nStokes I, Q, U and V profiles in FeI 630.15 and 630.25 nm lines, Stokes I and V\nprofiles in the CaII 854.2 nm line and Stokes I profile in the HeI 1083.0 nm line.\nSpatial resolution is 1.0 by 1.0 arcsec over a 2048 by 2048 arcsec field\n(covering the solar disk).  Scan rate is variable between 0.05 and 5.0 s/arcsec.\nThe VSM provides the following core science data products: (a) photospheric\nfull-disk vector-magnetograms using the FeI 630.15 and 630.25 nm lines\n(field strength, azimuth, inclination, flux, Doppler velocity, continuum intensity);\n(b) chromospheric full-disk magnetograms using the CaII 854.2 nm line (line-of-sight\nmagnetic flux, Doppler velocity, line core intensity); (c) full-disk HeI 1083.0 nm\nline characteristics (equivalent width, continuum intensity, Doppler velocity, line\ndepth, line asymmetry, Doppler width, Si line width, Si line depth, Si Doppler\nvelocity); (d) photospheric full-disk longitudinal magnetograms using the FeI 630.15\nand 630.25 nm lines (line-of-sight magnetic flux).  Data products (a) to (c) are\nproduced three times a day while data product (d) were expected to be be produced\nonce a day.",
