Direct imaging PCA pipelines

DISCLAIMERS: work in progress, open source, as is, no guarantees.


NEW PYTHON PIPELINE from Carlos Gomez (University of Liege)

OLD IDL PIPELINE (OBSOLETE)

QUESTIONS AND COMMENTS: please send me a personal e-mail.

DESCRIPTION: a package implementing my version of Principal Component Analysis (PCA) following Soummer et al. 2012 (ApJL 755, L28). The package includes “smart-PCA” for reduced sensitivity to throughput losses as well as fake companion injection for their precise calibration. 

INSTALLATION NOTES: uncompress the zip file in your ASTROLIB directory (ASTROLIBs are required), or in any directory in your IDL path. Move and duplicate the CALL_PCA.PRO file in the directory where your pre-reduced cubes and parallactic angle fits files are. Input file name convention: “img_targetname_dc.fits”, and “vec_targetname_paral.fits”.
