... Posts tagged ?parameter estimation? ... Leccardi & Molendi (2007) have a paper in A&A ( astro-ph/0705.4199 ) discussing the biases in parameter estimation when spectral fitting is confronted with low counts data. Not surprisingly, they find that the bias is higher for lower counts, for standard chisq compared to C-stat, for grouped data compared to ungrouped. ...

... 8, ``Celestial Mechanics'', 2002 Station coordinates from observations of DORIS system TOPEX/Poseidon satellite M. V. Vasiliev, E. I. Yagudina Institute of Applied Astronomy, St. Petersburg, Russia The satellite system DORIS (Doppler Orbitography and Radiopositioning In­ tegrated by Satellites System) is the effective means of space geodesy and geody­ namics. ... Along with SLR, GPS observations of DORIS system are used also for EOP parameters de­ termination. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

DayNumber: Even though this number is in the data, some packet headers have the wrong number and it makes it a whole lot easier to have the user check and enter this number correctly. ... CONSTRICTOR will add a multiple of 24 hours to the time tag when the day number changes. Remember to set the StopTime to, say, 48 hours if you use a DayNumber of one less than the actual day number. ...
