1. Lindler et al.: Star Detection, Astrometry, and Photometry
We have evaluated various image restoration techniques (both linear and non-linear) applied to a simulated crowded star field observed with the HST Planetary Camera (PC). Evaluation criteria included star detection, astrometry, and photometry. ... The non-linear methods give much better star detection and slightly better astrometry results. Aperture photometry measurements in images restored with the non-linear restoration methods show significant non-linearities. ...

2. Limits on Phase Correction Performance Due to Differences Between Astronomical
... Bojan Nikolic web pages (r. 329) . ... Using high-resolution three-dimensional realisations of turbulent fields, we investigate the limits on achievable performance of atmospheric phase correction using water-vapour radiometers arising from following effects: the incoherent measurement of power from water by the radiometers (in contrast to coherent detection of the astronomical signal); the different tapers of the response patterns of the astronomical and radiometer receivers; and, the ...

5. Positive Iterative Deconvolution in Comparison to Richardson-Lucy Like
... Positive iterative deconvolution is an algorithm that applies non-linear constraints, conserves energy, and delivers stable results at high noise-levels. This is also true for Richardson-Lucy like algorithms which follow a statistical approach to the deconvolution problem. ... All algorithms resolve the objects, as shown by the reconstructions by Richardson-Lucy in Figure 2 on the right, the algorithm by M?ller in Figure 3 on the left and positive iterative deconvolution in Figure 3 on the right. ...

The HyperNews Linux KHG Discussion Pages . Forum: The Linux Kernel Hackers' Guide . Date: Wed, 07 Jan 1998 14:23:15 GMT . ... We are doing a project that required us to change some chatacteristics of the TCP protocols and/or add a buffer into the TCP layer also. It seems to us that the SOCK_RAW or SOCK_PACKET are good choice to override the TCP or even IP level of the networking software. Unfortunately, we cannot find any documents or sample programs about SOCK_RAW or SOCK_PACKET.. ...
