Abstract

Integral-field spectrograph (IFS) instruments are well suited to observe extended and faint objects, such as planetary nebulæ and galaxies. A result of such observations are large quantities of raw data, which mostly require an expert to derive accurate scientific spectra. Most instruments handle up to several thousand spectra simultaneously, using a unique file format, together with numerous instrument-specific issues, which only an experienced expert can resolve. p3d is an open source processing tool that is designed to handle raw data of any fiber-fed IFS, reducing IFS data quickly, easily, and accurately. Separate tools are available that handle many tasks including cosmic-ray hit rejection in single spectrum images, the combination of images, tracing of spectra on the detector, determination of spatial profiles of any shape, handling of images for flat fielding, dierent versions of spectrum extraction, combination of multi-detector data, and correction for atmospheric dierential refraction. The same approach and code is used with all instruments. No license is required when using p3d, even though it is based on the proprietary software IDL; this is made possible through precompiled binary files that are distributed together with the source code. p3d has been much improved with numerous releases since the first version early in 2010. Here we present the latest capabilities of a nearly complete program.
