Next: RGCV for Steepest Up: Generalized Cross-Validation as a Previous: The Richardson-Lucy Algorithm . Cross-validation divides the data into two sets. ... Extending this concept, generalized cross-validation (GCV) uses each data point as the testing set, and then averages a weighted prediction error over the entire data set (Golub et al. ... The main drawback of the GCV criterion comes from the denominator of . ... and is now called the Randomized GCV (RGCV) criterion. ...

At certain times, the teacher may close a complete course, or a unit, or an exercise. These perhaps represent parts of the course which are under development, or which must be kept unmodified for administrative reasons. Dave.Marshall@cm.cf.ac.uk . Wed Sep 14 10:06:31 BST 1994

... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... omdetect (omdetect-5.14.2) [?? Meta Index / Home Page / Algorithm Omdetect will find sources on an image using both a peak-finding and connected-pixel algorithm. The former will mainly detect ``point'' sources and the latter ``extended'' sources. The peak-finding algorithm is used first to try to locate all point sources, in order of decreasing brightness. This algorithm mainly overcomes problems with modular-8 patterns around bright sources and scattered light features. ...

... Will there be interactive user accounts (telnet/SSH)? Will users be using it as a workstation or is it a server? ... The main difference in today's world between computers is usually not the hardware, or even the OS (Linux is Linux, NT Server and NT Workstation are close family, etc.), it is in what software packages are loaded (Apache, X, etc) and how users access the machine (interactively, at the console, and so forth). ...

... This chapter describes the PEPSYS package for general photometric reductions. The function of photometric reductions is to measure and remove, so far as possible, the instrumental signature from the data. ... The package contains two main parts: a planning program and a reduction program. The planning program interacts with the user to find out the goals of the observing program, and then produces a schedule of the observations needed to meet those goals efficiently. ...

For non-spherical isotropic particles, the classic variant of the RDG approximation does not include the anisotropy of the shape and hence does not give the correct Rayleigh limit, say, for small ellipsoids. ... We call this variant a modified RDG approximation (MRDG). ... First, the MRDG leads to the correct Rayleigh limit. ... The second approach to generalization of the RDG is connected with the use of the Born iterations for the scattering integral equation [ 95 , 124 , 132 , 264 ]. ...
