FIG. 2.—Gray‐scale images of the flux‐calibrated WFPC2 PC continuum images of η Car. (a) F336W (near‐UV); (b) F410M (blue); (c) F631N (red); and (d) F1042M (near‐IR). North is up and east is left. The images are all displayed with the same (logarithmic) intensity stretch to highlight changes in contrast between light and dark regions with wavelength. The intensity stretch is between 9.5 × 10⁻¹⁹ ergs cm⁻² s⁻¹ Å⁻¹ (black) and 5.0 × 10⁻¹⁵ ergs cm⁻² s⁻¹ Å⁻¹ (white). The central star is at coordinates (0^{﹩\arcsec﹩}, 0^{﹩\arcsec﹩}) in each image. The celestial coordinates of the central star are α = 10^h45^m03﹩\fs﹩6, δ = −59°41^{﹩\arcmin﹩}04^{﹩\arcsec﹩} (J2000.0), with an uncertainty of less than 1^{﹩\arcsec﹩}.
