Pipeline architecture design, initial algorithms development, core structure, GUI frameworks, and many primitives by Jerome Maire and Marshall Perrin.
Patrick Ingraham developed many primitives, led major aspects of IFS calibration and testing, and extensively contributed to analyses and documentation. Dmitry Savransky made major contributions to pipeline primitives, infrastructure, and GPItv.
Sebastian Bruzzone developed methods for satellite spot measurements in polarization mode. Zack Draper developed improved datacube extraction routines and tools for fitting flexure using microlens PSFs, and an alternate bad pixel fitting code. Mike Fitzgerald contributed improvements to gpitv and polarimetric extraction, and to distortion correction. Kate Follette contributed fixes and improvements to several primitives, and overall assisted with pipeline maintenance and releases. Alexandra Greenbaum improved recipes for nonredundant aperture masking with GPI, and also contributed to this documentation. Li-Wei Hung contributed improvements to polarization related primitives, particularly photometric calibration in pol mode, and measurement of FPM position. Doug Long made some improvements to interpixel capacitance (IPC) correction code. Christian Marois contributed to improving PSF subtraction algorithms and contrast measurement code. Max Millar-Blanchaer contributed extensively to polarization mode primitives and GPItv polarization support, along with calibration of polarimetric performance. Eric Nielsen improved parallactic angle calculations, updated documentation, and contributed improvements to gpitv. Abhijith Rajan found and fixed several bugs. Jean-Baptiste “JB” Ruffio vanquished many bugs, enhanced the destriping and microphonics removal primitives, and wrote portions of the documentation. Naru Sarakuni extensively supported integration and test, and contributed improvements to GPItv. Jason Wang contributed to satellite spot fitting, improved the installation system, and contributed improvements to GPItv. Schuyler Wolff developed and tested the PSF-fitting wavelength calibration algorithm, improved the Data Parser, made other pipeline improvements, and contributed significantly to this documentation. Joe Zalesky contributed improvements to sat spot measurement algorithms.
Jeff Chilcote provided guidance on detector operations and calibrations. Tyler Barker implemented the KLIP algorithm, under guidance from Dmitry. Steven Beckwith analyzed detector testing data to assess optimal readout modes. Quinn Konopacky developed the distortion correction primitive along with Jerome and Mike. Franck Marchis oversees the computer infrastructure at the SETI Institute hosting software repositories and documentation, and supervised visiting student JB Ruffio. Laurent Pueyo contributed to data analyses and algorithms development. Sloane Wiktorowicz worked with Max to calibrate the instrumental polarization. Some utility functions used in the pipeline are by Mathilde Bealieau, David Lafreniere, Jean-Francois Lavigne, and Lisa Poyneer.
Contributions to data analyses and public data releases have been made by many additional members of the GPI Data Analysis team, including Rob de Rosa, Jennifer Patience, Sandrine Thomas and Kim Ward-Duong.
Rene Doyon was subsystem PI for the GPI DRP as part of the GPI project, and provided top-level guidance in overall pipeline design. James Graham developed core algorithm concepts for the polarization reduction, which were subsequently implemented by Marshall and enhanced by Max. Bruce Macintosh maintained overall coherence of the GPI project wavefront with crucial contributions by Dave Palmer and Les Saddlemyer.
From Gemini, Stephen Goodsell kept the project on track. Carlos Quiroz and Fredrik Rantakyro supported the Gemini Data System, including establishment of interfaces and extensive implementation and testing. Pascale Hibon helped with testing of the pipeline and operations at Gemini. Kathleen Labrie provided valuable input from Gemini’s perspective during software reviews.
The GPI pipeline software architecture was inspired by, and portions of the backbone code re-used from, the Keck OSIRIS pipeline. The OSIRIS pipeline was developed by James Larkin, Shelley Wright, Jason Weiss, Mike McElwain, Marshall Perrin, Christof Iserlohe, Alfred Krabbe, Tom Gasaway, and Tommer Wizanski.
The Recipe Editor was inspired by the OSIRIS ODRFGUI, orginally written in Java by Jason Weiss. Jerome Maire and Marshall Perrin reimplemented it in a modified form in IDL, with improvements since contributed by several team members.
GPItv is based on atv by Aaron Barth et al. The Header Viewer dialog in gpitv is taken from the OSIRIS Quicklook tool ql2, itself derived from the NIRC2/NIRspec quicklook. The “Browse Files” dialog is based upon code derived from David Fanning’s tool selectimage.pro.
The GPI data pipeline is built upon an extensive foundation of other open source software from the astronomical community, including but not limited to the Goddard IDL Astronomy Pipeline, the JHUAPL library, Craig Markwardt’s MPFIT library, Liam Gumley’s IMDISP.PRO, and many other individual tools. See the licenses file provided in the pipeline source code’s external directory for a complete list of all open source routines we’ve made use of.
