... CentralProcessor 0.11 documentation . BETA Processing Pipelines . ASKAPsoft is the suite of processing software developed by the ASKAP computing team to handle the pipeline processing of ASKAP observations. ... BETA processing uses a slightly different approach, particularly in the calibration method, and the set of scripts detailed here are designed to demonstrate a BETA reduction approach with ASKAPsoft. ...

... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...

... 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. ...

... Moscow, Russia E-mail: krivosheev@iki.rssi.ru Notes: · · The Monte Carlo method (s) is also called the statistical test method An innumerable number of processes can be listed the outcome of which is not determined and has probabilistic nature, but these processes obey statistical laws, so to obtain the result we have to make multiple similar tests, i.e. to use the MC method Because probabilistic processes are widely spread in nature, the MC ...

Next: How the Data Up: CCD Reductions Previous: Combine Example . Having obtained some background, let us now start to process the input frames according to the scheme in Section . As indicated in that section the reduction sequence is, in a simplified version the calibration of science frames consists of the following steps: . determine overscan correction and trim area; . preparing calibration frames; . ...

Next: Filtering ROSAT HRI data Up: ROSAT HRI Recipes Previous: Correlating Spectral Data with . Although the spatial variation of the quantum efficiency across the HRI is nominally within 10% for most of the detector, occasionally it may be desirable to flat-field a map with preflight calibration measurements. ... Store the new gain map image using ``blink" in SaoImage. ... The quantum efficiency correction (QEC) is the inverse of the intensity determined from the QE map at the source position. ...

SAS home . ... List of SAS threads . OM data processing from A to Z is performed by two "chains": omichain and omfchain , for image and fast mode data respectively. ... Then a source detection algorithm is used to identify the sources present in the image. ... A final source list is obtained from all exposures and filters. ... If the user has PPS products from the processing of his/her observation, or from the XSA, then the first thing to do is to overlay the image source list onto the sky image. ...
