... Compute the source position in DET coordinates [xdet, ydet] from sourcex , sourcey : If the input coordinate system (form sourcecoords ) is POS, convert sourcex , sourcey to EQPOS, using the attributes REFXCRVL and REFYCRVL from the spectrum as the reference point, then convert to DET using the spacecraft attitude at the start of the observation, taken from the OAL. ... Use xdet, ydet to determine the source position in TELCOORDs and compute mirror_area for that position. ... end energy loop . ...

For some observations, a significant amount of data may have been rejected during SASS processing because the background level was higher than the calculated threshold for rejection. ... REJECTED EVENTS . ... The recipe will allow the user to include rejected events in the generation of a new qpoe file and filter on the background level. ... This creates a qpoe file with standard + rejected events. ...

... Previous: Background Fluctuation Analysis from the Multiscale Entropy . ... A new measure of information is defined which is based on noise modeling and incorporates resolution scale. Properties of this measure are discussed. ... Additionally it allows for image noise modeling, and subsequent noise removal. ... Hence information- and entropy-based processing technologies will be necessary for the effective design and implementation of large, future generation, image databases. ...

An improved correlator for ALMA has been proposed by an European consortium including Astron (NL), Bordeaux University (FR), IRAM (FR) and Arcetri. ... The work in Arcetri has focused on the efficent design of a digital receiver, that exploits the peculiarities of the astronomical signal, i.e. the extremely coarse quantization and the stochastic nature of the input signal. ...
