... 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 . ...

... Most data from ATNF observatories distinguishes on and off source data using the file name. This makes it easy to create two scantables with the source and reference data. As long as there was exactly one reference observation for each on source observation for following method will work. For Mopra and Parkes data: ASAP> r = scans.get_scan('*_R') ASAP> s = scans.get_scan('*_S') . For Tidbinbilla data ASAP> r = scans.get_scan('*_[ew]') ASAP> s = scans.get_scan('*_[^ew]') . ...

... This step is done mostly interactively and uses some basic ad-hoc IDL procedures, mainly for testing and checking of the consistency of the results.Once the observations have been selected and the count spectra extracted, the available spectra of each background level are accumulated. ... Average QUALITY such that QUALITY =0|1 Exposure times are added and the total is written in the EXPOSURE keyword of the header of the output FITS file. Finally, the CCFs are built from these templates. ...
