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? . ...

... The telluric features redward of 6700 A have been removed from the accurate spectro photometric standards of Hamuy et al. to permit more reliable relative and absolute spectrophotometry to be obtained from CCD spectra. Smooth яuxes from 3300 to 10500 A are best determined by dividing the raw spectra of all objects taken in a night by the raw spectrum of a "" smooth оо spectrum star before deriving the instrumental response function using the revised standard star яuxes. ...
