X-ray and optical images for four new spectroscopically confirmed CVs from CSC2–Gaia DR3 catalog. Left: False-color Chandra X-ray images in the 0.5–7 keV energy band. The images were smoothed using a Gaussian kernel with different widths equal to 1 − 3 times the PSF radius, depending on the source counts. Right: Composite optical images based on Pan-STARRS i, r, and g filter data. The white boxes show the field of view of the optical images on the right. Circles: a PSF radius equal to the 90% of encircled counts fraction (solid white line), and a radius equal to the semimajor axis of the error ellipse (95% localization error) centered on the source X-ray position (dashed magenta line).
