Next: GEOHIEL Up: Details of SCHED Parameters Previous: GAP Contents . GEOBACK is a knob sticking out of the algorithm that selects sources for use in a geodetic segment. ... For each new source, SCHED looks for which sources of those available would conribute the most to improving the rms of the SecZ parameters in a dummy fit. That dummy fit does not use all the sources in the segment so far, but rather is restricted to the last GEOBACK sources. ... Example: geoback=10 . ...

Plans are under way to create a new way of performing non-interactive observations which will be called auto-observing . ... Non-interactive observing with CIMA has for a long time been available with the use of CIMA command files. Contrary to normal command file observing which requires a command file with a set of commands to be executed sequentially, auto-observing will use a list of sources and a list of instructions on how to observe each of the sources. ...

Detecting Variations in Source Intensity for Poisson Data Y. Yu, XL. Meng, D. van Dyk, V. Kashyap, and A. Zezas Abstract The analysis of light curves is an especially challenging statistical task for low-count Poisson data: Variation in the source intensity may be shadowed by the Poisson variation of the counts. Here we discuss a class of statistical models that are designed to capture trends and autocorrelations in Poisson data that are collected over time. ... Example: A downward trend? . ...

Abstract: The calculation of flux upper limits in the source-free ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... The principal component in this is the time taken to pre-process and handle the 30 GB of RASS data rather than the calculation of each upper limit. ...
