  We carried out polarimetric observations of the white-light corona during the
total solar eclipses that occurred on 2017 August 21 and 2019 July 2, and
successfully obtained data at two different sites for both eclipses. After
eliminating the sky background, we derived the brightness, polarization
brightness, and degree of the polarization of the K+F corona from just above
the limb to approximately 4 $R_\odot$. Furthermore, we isolated the K- and
F-corona with plausible degree of polarization of the K-corona. The field of
view covering up to approximately 4 $R_\odot$ enabled us to compare the derived
brightness and polarization with a wide range of other observations. The
results of the comparison show significant scatter; while some of the
observations present very good coincidence with our results, the other ones
exhibit systematic discrepancy.
