Downloadp3d is a general data-reduction tool for use with fiber-fed integral-field spectrographs (IFSs); although, the spectrum viewer works with spectrum data cubes of any origin. The tool is built about the proprietary software IDL (Harris/EXELIS; see http://www.harrisgeospatial.com), but can be used without any license. Most slowly running loops are implemented in parallelized C (OpenMP).
Features
- p3d works on all platforms supported by IDL.
- p3d can be used with full functionality without an IDL license.
- Optimal extraction, including correction for so-called cross-talk.
- Flux calibration can be done both interactively and non interactively.
- Can correct data for differential atmospheric refraction.
- Single images are cleaned of cosmic-ray hits - using IFS-specific approaches that work paricularly well with oversampled data.
- Time-consuming tasks are implemented in (automatically) compiled C, using OpenMP.
- Information on all operations are (optionally) saved to log files.
- p3d currently supports thirteen IFUs - more can be added on request.
- Calar Alto 3.5m / PMAS (LARR+PPAK, old and new CCD).
- McDonald Observatory 2.7m / VIRUS-P (fiber bundles 1,2, and VP2.7).
- McDonald Observatory 2.7m / VIRUS-W.
- AAT 3.9m / AAOMEGA/SAMI (basic support, could be improved upon request)
- AAT 3.9m / AAOMEGA/SPIRAL (blue and red arms).
- ESO VLT/UT3 / VIMOS (all HR and MR-modes, old and new configurations).
- ESO VLT/UT2 / FLAMES (the ARGUS IFU, and the two mini-IFUs).
- BTA 6m / MPFS (the new CCD).
- WHT 4m / INTEGRAL/SB1-3 (both the old and the new CCDs).
- Gemini North and South 8m / GMOS-N and GMOS-S (one-slit modes).
- ERA2 / An AIP integral-field spectrograph for life sciences.
- Allows use of either a master-bias image or prescan and overscan bias regions.
- The spectrum viewer can be used with all output of the "CALIFA" data-reduction pipeline.
- The spectrum viewer accepts reduced data cubes of the MUSE pipeline (all sizes, RAM permitting; no args. required).
- All IDL source files have the prefix p3d_, i.e. no interference with other IDL programs.
- Output data cubes (ver. >=2.2) can be viewed with the ESO / CASA viewer.
- Tutorials for: data-reduction, visualization, and p3d setup.
- Contains tool to generate simulated data.

P3d is a mature tool, OpenMP support helps me with large data sets.
-
Am using it for my astrophysics projects to generate 3D spectral cubes... works seamlessly in this regard.

I could not have written my PhD thesis without p3d. In my thesis I worked on data from ~10 nights of observations with the PMAS/Lens Array Integral Field Spectrograph at Calar Alto. Ineed, the data contained fantasting science results, and p3d helped me to create high-level datacubes from the original raw data.

p3d is fantastic!

P3d is the best! Thanks.
