p3d / News: Recent posts

This release contains a number of bug fixes that make
p3d easier to use...see the NEWS file.

Add a web page for quick information on how to view
publicly available data cubes of MUSE. The page is
available through https://p3d.sourceforge.io/MUSE,
which is short for https://p3d.sourceforge.io/index.php?page=MUSE.

This release contains one major new features:
o Adds the new simulated instrument 3D-Cancerspec,
which is defined as the instrument "ramcancer".
The simulation tool p3d_csim first creates simulated
raw data for this instrument, and thereafter these
data can be reduced as usual. A new feature is that
the number of spectra can be set on the fly to use
values in the range 100-1000; obviously 1000 spectra
are too many to fit on a 2048x2048 pixel CCD, but
now it is easy to study how many spectra are feasible
to allow meaningful reduced results.
Also add a tutorial that shows how data can be simulated
and then reduced.
o Fix some minor bugs in the dispersion-mask creation
tool, which, under certain circumstances, will make the
creation of such dispersion masks less problematic.

This release contains two major new features:
o Support for the new non-IFU instrument PAWS.
o A revamped queue system that uses IDL's
asynchronous queue functions for a more
stable functionality.

This release mainly contains files and content to
support reductions using the instrument PRAXIS.

The description on how to compile the C routines
on Mac / Darwin platforms has been extended to
be more informative on what needs to be done to
install gcc (with OpenMP support).

Some bug fixes.

This new release contains:
o Further fixes and improvements to the spectrum viewer. Notably:

+ Support for, so-called, beam-switched data (which few users can
    make use of at the moment).
+ Spectra can now be exported as plain-text files by chosing the
    appropriate new entry in the File menu.
+ The spectrum viewer can now be readily used with data cubess
    of the MaNGA instrument.
+ Adjust the state files so that the spectrum viewer can be launched
    with the settings of the previous session when no arguments or
    keywords are provided when the tool is launched; this now works
    for cubes as well as row-stacked-spectrum (RSS) files.
+ Various smaller corrections.

o Spectrum extraction: add a version of 'direct pixelwise subtraction'
that works with overlapping spectra in beam-switched data.
o Add a new instrument: R10E-Atik, which is another life-sciences
instrument setup at the AIP.
o Fix various bugs.
o p3d now requires IDL version 8.7.1 when there is no IDL license;
please ask our friendly support team for a p3d-specific IDL
distribution if you'd need this distribution.

Version 2.6.1 adds a number of bug fixes to the spectrum viewer (p3d_sv),
the p3d main GUI, the line fitting tool (p3d_ifsfit) and spectrum extraction.

New features include support for the instrument MRS2 (through the MRS1
files), including support for reduction of so-called beam-switched data; the
tutorial for MRS1 has been augmented with information on MRS2.

The tophat extraction is now done using parallelized C code, when the
required C compiler (gcc) is available .

And especially after I manage to commit the final fixes
(the svn servers at Sourceforge seem to be down at the moment).

This version mainly adds new functionality to the spectrum viewer:
o Save and load the GUI setup using "state" files.
o The saving of line-fit log files has been improved with a new
target-setup panel, which also makes it possible to setup the
files to save when clicking the "Save Files / Log Fit" button.
The setup includes the addition of target name, type, comment
as well as calculated target coordinates (RA, DEC) to the line-fit
log file. The additional files that can be written with one click
include the currently viewed spectrum, spatial map, and region.
o The FONT keyword now works as intended; set this keyword
to the name of a fixed-space font on your computer. Most useful
when using a large screen, with say >= 4K resolution.

This minor release adds better support for simulations using the tool p3d_csim. The tool now accepts one-dimensional kernels as well as two-dimensional kernels that describe how the dispersion and cross-dispersion profiles appear across the detector for all spectra at all wavelengths.

This minor release adds new functionality to the tool p3d_ifsfit. Specifically, it is now possible to specify a two-dimensional redshift map, which should allow more accurate fits when the redshift varies strongly across the field.

This major release presents a more mature version of the previous minor releases.
New features include:
o Data-reduction and visualization tutorials for three instrument setups,
and a p3d setup tutorial for one instrument.
o A new tool that simulates IFU data, p3d_csim. The new data can then be reduced
with the other tools of p3d.
o A number of important bug fixes.

This minor release adds a new tool that creates simulated raw data for the selected instrument setup (p3d_csim). So far, the new instrument setup "mosms" includes the necesary data file to use this tool.

This minor release adds six tutorials on the data reduction and visualization of data of the three instrument setups MRS1, PMAS/Larr, and PMAS/PPak. The tutorials are available in the form of LaTeX/PDF documents and reduction and launch scripts written in three different languages. There are also a number of important bug fixes that permit all scripts to run as intended.

This minor release adds a tutorial on the MRS1 instrument configuration, along with some additional minor bug fixes.

This major new release features drastically improved support for data cubes in the spectrum viewer and line fitting tools. The spectrum viewer now contains basic functionality for pretty advanced analysis on regions and lines in the spectrum viewer.

This major new release features new line-fitting tools and a much extended spectrum viewer, which now also loads and views data cubes - the tool can load and view cubes of 100GB and more (if enough RAM is available). Also numerous bug fixes and adjustments to provide a more stable tool.

The latest release of p3d, 2.2.6 "Serenity", is now available.

This release mainly contains a number of bug fixes, and
some minor improvements.

In this release the C-based scattered-light correction
routine works (again). And the C-based cosmic-ray
cleaning is now working as intended.

The latest release of p3d, 2.2.5 "Serenity", is now available.

This release mainly contains a number of bug fixes, in
particular to the C-based routines.

The latest release of p3d, 2.2.4.1 "Serenity", is now available.

This is an important update, which fixes several severe bugs in
releases 2.2.2, 2.2.3, and 2.2.4. Please update to this version,
and do not use the mentioned releases for serious scientific work.

The latest release of p3d, 2.2.4 "Serenity", is now available.

This release contains one bug fix that allows the parallelized C version of the cosmic-ray cleaning routine L.A. Cosmic to work properly.

The latest release of p3d, 2.2.3 "Serenity", is now available.

This release contains a potentially major big fix in comparison to release 2.2.2.

The latest release of p3d, 2.2.2 "Serenity", is now available.

This release contains, mainly, a number of bug fixes. Also, however, several slow routines have been replaced with parallelized C routines. The way p3d is launched is completely overworked. From now on p3d uses a p3d queue system, which makes it comfortable to work with p3d without an IDL license.

The latest release of p3d, 2.2.1 "Serenity", is now available. This minor release contains one important bug fix, which allows created dispersion masks to be saved again.

The latest release of p3d, 2.2 "Serenity", is now available. This major release contains numerous bug fixes, along with important new functionality.
