... Archives . ... The PCA and ICA is used for separating mixed components with some assumptions. ... The need of source separation methods in astronomy has led various adaptations of decomposition methods available. ... I rarely come up with a paper which gathered and summarized component separation methods applicable to astronomical data. In that regards, the following paper seems useful to overview methods of reducing dimensionality for astronomers. [arxiv:0805.0269] . ... Chandra Blog . ...

The individual tables for each instrument are accessed through a system using a master component table and a master graph table. ... For history tracking reasons, we rename all of the master component and graph tables and keep them in a separate directory called MTAB . The MTAB directory contains HST master component and graph tables which have been delivered to OPUS, renamed using the uniqname schema. ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...

Next: Creation of the Up: The Data Organizer Previous: Checking the quality . The association of scientific frames with suitable calibration images is achieved by selecting and ranking all calibration frames which for a given scientific exposure match a set of user defined selection criteria. ... For instance, this may in natural language be expressed as: ``Find for each scientific frame 2 dark exposures which have been observed within the same night. ...
