... Some Problems of Practical Image Restoration . Abstract:. ... This discussion begins by noting that stellar photometry is often done quite effectively on unrestored images. ...
... Examples of f /48 images, f /48 longslit spectra, and prism images appear in later ... images in this section are displayed with higher intensities as white and lower ... image has been fully calibrated by the FOC pipeline and shows features that are ...
... Space Telescope Imaging Spectrograph . MAMA Pixel to pixel flat-field image. ... Space Telescope Imaging Spectrograph . MAMA Pixel to pixel flat-field image. ...
... The roughly 5 images per dither position were cosmic-ray rejected and stacked into a single image. ... images were aligned and combined using the drizzle algorithm, which corrects for geometric distortion, and produces an output ...
... Most of the galaxies imaged are likely to be too faint for spectroscopy to be obtained with even the largest ground-based telescopes, and therefore a broad wavelength baseline was chosen for the images in order to maximize the discrimination of any ...
... Image Restorations of High Photometric Quality . Abstract:. ... An image restoration technique is described that achieves high photometric accuracy for both stars and distributed emission. ...
