pynpoint 0.6.0

Pipeline for processing and analysis of high-contrast imaging data

Python package for processing and analysis of high-contrast imaging data

PynPoint is an end-to-end pipeline for the data reduction of high-contrast imaging data of planetary and substellar companions, as well as circumstellar disks in scattered light.

The pipeline has a modular architecture with a central data storage in which the reduction steps are stored by the processing modules. These modules have specific tasks such as the subtraction of the background, frame selection, centering, PSF subtraction, and photometric and astrometric measurements. The tags from the central data storage can be written to FITS, HDF5, and text files with the available IO modules.

PynPoint is under continuous development and the latest implementations can be pulled from Github repository. Bug reports, requests for new features, and contributions in the form of new processing modules are highly appreciated. Instructions for writing of modules are provided in the documentation. Bug reports and functionality requests can be provided by creating an issue on the Github page.

Documentation

Documentation can be found at http://pynpoint.readthedocs.io, including installation instructions, details on the architecture of PynPoint, and end-to-end example for data obtained with dithering, and a description of the various processing modules and parameters.
