Chandra-ACIS images of 1H 0419-577 (top left) and of the point-like source PKS 2126-158 (top right) in the 0.2–1.0 keV band. As a visual aid, we also show the color bar of these two images at the bottom. For comparison, we show in both the panels a circle with the radius of the core of the Chandra PSF. Bottom left: same as first panel, smoothed using a Gaussian kernel of 3 pixels. The regions that we used for spectral extraction are overlaid. We also mark the direction from which we removed the ACIS readout streak (dashed line) and the location of possible extended filaments around the source. Bottom right: false-color image obtained using the PSF-deconvolved 0.2–0.5, 0.5–2.0, and 2.0–7.0 keV band images as red, green, and blue, respectively.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
