p3d 2.6.2 freeware

p3d is a general data-reduction tool that is intended to be used with data of fiber-fed integral field spectrographs (IFSs). This tool can be useful for people who have access to astronomical data of such an instrument. Data-reduction tasks, which are performed by p3d, convert raw data of CCD detectors into extracted spectra that can thereafter be used for scientific purposes. ...

2.6.2 Dec 28, 2018 New Release New functionality and bug fixes
- The spectrum viewer now handles image (files) that contain a second
image in the extension BSW_DATA; this second image could contain
so-called laser offset, or beam-switched, spectra that are offset from
the regular spectra. The user can select between the regular spectra,
the [laser] offset spectra, the difference between the two, and a,
so-called, laser normalized difference between the two using the new
droplist widget on the Extra control panel or using the new menu entries
in the "Image View" menu. Two additional widgets allow the offset BSW
data to be multiplied with a factor before the offset spectra are
subtracted from the nominal spectra; the default multiplication factor
is 1.0.
- Add File menu entries to look at the FITS file headers of the BSW_DATA
and BSW_ERR extensions, when they are present.
2.2.4.1 Jun 21, 2013 New Release All tools that combine raw-data images:
· Major bug fix - When I optimized the C routine of the image combination routine I introduced a serious bug. This bug is present in revisions 2753-2779 of p3d_cimcom.c, and is fixed with revision >=2780

C routines:
· Optimization - Optimized the C routines p3d_cpixex.c and p3d_cmpd.c
