... Astronomical image processing applies a large variety of numerical methods to extract scientific results from observed data. The standard computational techniques used in this process are discussed with special emphasis on the problems and advantages associated with them when applied to astronomical data. ... In Section the transformation of raw observed data into intensity calibrated values is discussed while general image processing techniques are reviewed in Section . ... Basic Concepts . ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... The existing package features many applications which are required for the next generation telescopes under development (e.g., multi-field, multi-scale, and wide field imaging algorithms, full primary beam Stokes I,Q,U,V imaging, automated and interactive statistical data editing, flexible calibration and self-calibration based on the telescope measurement equation; we highlight some of this functionality and discuss the future directions for the applications and underlying technology. ...

... GPI Data Pipeline 1.0 documentation . ... Let?s consider in turn each major topic that must be addressed during the processing of GPI data. ... Our goal here is not to document pipeline software (though that will be discussed) but rather to document our understanding of the properties and performance of the instrument itself, in terms of their effects on data processing. This document is not intended as a complete guide to achieving science-grade calibrations of your GPI science data! ...

... A tutorial on multispectral imaging of paintings using the Mona Lisa as a case study . ... Conclusions: In this article, we have presented a tutorial description of the multispectral acquisition of images from a signal processing point of view. ... I wonder if there?s literature in astronomy matching this tutorial from which we may expand and improve current astronomical photometry processes by adopting strategies developed by more populated signal/image processing engineers and statisticians. ...
