RX J0953.1+1458. Left, top: combined blue and red flux-calibrated medium-resolution spectra at orbital maximum and minimum. Second from top: zoom into a difference spectrum emphasizing the Hα Zeeman features. Third from top: mean radial-velocity curves of the narrow and broad emission-line components of Hα. Bottom: O − C diagram for the center of the bright phase of the optical light curves. Right, top: overall spectral energy distribution, involving nonsimultaneous data (see text). Center: optical light curves taken in WL, taken in 1995, 2010, 2015, and 2019, shifted by multiples of 0.25 units in the ordinate. Bottom: PSPC X-ray light curve taken in the RASS. The photometric phase is from Eq. (7).
