Left: Part of the HST/WFPC2 image of PKS 1830−211. This image is a combination of all available frames in the F814W filter (eight in total), for a total exposure time of 6400 s. Right: Simultaneous deconvolution of the eight frames (see text), reaching a resolution of 0﹩\farcs﹩046, and sampled with a pixel of 0﹩\farcs﹩023. The various positions of the two probable lenses and of the very obscured (and hence invisible here) QSO B are indicated with circles. Note the obvious spiral shape between the quasar images, with one spiral arm passing right onto the line of sight to QSO B. We identify this galaxy as the probable source of absorption at ﹩z=0.89﹩. The center of the ellipse shown in this figure defines the barycenter SA of the spiral (see main text). It is one of three centers, together with SP and G, considered in the modeling. There is no significant trace in this image of the much redder lens G, but we plot its position as measured from the near‐IR F160W image, in overlay on the F814W image.
