CLASP2, the Chromospheric LAyer
SpectroPolarimeter is the second
flight of a sounding rocket designed to investigate the magnetic field
of the upper chromosphere. Flight data was taken 2019-04-11 from 16:51:31 -
16:58:56. The context Slit Jaw imager remains unchanged from the first
flight and observes in a bandpass with ~3.5nm FWHM centered on 121.6nm
(Lyman-α). The two SpectroPolarimetric imagers observe in a
wavelength range of approximately 279.2-280.7nm (slight differences
between the two cameras) and capture the MgII h and k lines. The
flight data released here are raw, no calibration has been applied and
the SP data has not been demodulated into the Stokes parameters. Level
1 calibrated data will be available by April 2020 along with a Users
Guide and other documentation. Questions about CLASP2 can be directed
