1. Sample Shifting
... Moving the sample locations to achieve the desired warping will result in an irregularly sampled image plane. These irregularly spaced samples will then be brought back to regularly spaced positions, hence warping the image. ... The sampled impulse response, , is a function of the sample positions, . ... Allowing the sum to go outside the image boundaries ( or ) includes some ``anchor'' samples outside the image, which tends to stabilize the solution trajectory when is minimized. ...

4. Source Fitting and Positions
... Miriad has a couple of tasks available for finding positions of sources (see also cgcurs in Chapter 17 ). ... It fits a 2-D parabola to the image intensities in a 3 by 3 pixel box centred on the brightest pixel in a specified region and reports the fitted location and intensity. ... Input image . ... The quality of your fit can improve significantly by selecting a snug region, and/or using the clip keyword to keep pixel values with little signal (e.g. sidelobes and noise) out of the fitting process....

13. SDSS Slit-plate Deformation
... Slit-plate Deflection . ... One end of the approximately 2m long fiber is inserted into a hole in an aluminum plug-plate, and the other end is fed into and supported by a slit-plate. ... Since the fibers are to be calibrated from a fixed position, it will be necessary to know how much the slit-plate deflects under its own weight due to gravity, as well as how much it deflects under the weight of the fibers and harnesses. The deflection of two plates of thickness 3.175 and 3.607mm was tested. ...
