The Gemini Planet Imager (GPI) is a new facility instrument for the Gemini Observatory designed to detect
and characterize planets and debris disks orbiting nearby stars; its science camera is a near infrared integral
field spectrograph. We have developed a data pipeline for this instrument, which will be made publicly available
to the community. The GPI data reduction pipeline (DRP) incorporates all necessary image reduction and
calibration steps for high contrast imaging in both the spectral and polarimetric modes, including datacube
generation, wavelength solution, astrometric and photometric calibrations, and speckle suppression via ADI and
SSDI algorithms. It is implemented in IDL as a flexible modular system, and includes both command line and
graphical interface tools including a customized viewer for GPI datacubes.
This GPI data reduction pipeline is currently working very well, and is in use daily processing data during
the instrument’s ongoing integration and test period at UC Santa Cruz. Here we summarize the results from
recent pipeline tests, and present reductions of instrument test data taken with GPI. We will continue to refine
and improve these tools throughout the rest of GPI’s testing and commissioning, and they will be released to the
community, including both IDL source code and compiled versions that can be used without an IDL license.
