[c]TiRiFiC: Tilted Ring Fitting Code[/c][/b]
Abstract: Tilted Ring Fitting Code (TiRiFiC) is a prototype computer program to construct simulated (high-resolution) astronomical spectroscopic 3d-observations (data cubes) of simple kinematical and morphological models of rotating (galactic) disks. It is possible to automatically optimize the parameterizations of constructed model disks to fit spectroscopic (3d-) observations via a χ2 minimization. TiRiFiC is currently implemented as an add-on to the Groningen Image Processing System (GIPSY) software package and attempts to provide a method to automatically fit an extended tilted-ring model directly to a data cube.

Re: TiRiFiC: Tilted Ring Fitting Code
TiRiFiC v. 2.1.4 is out.
Introduced harmonic terms in radial and tangential velocity, introduced onset height above plane for change in velocity with z.
New parameters:
ZDRO=, ZDRA=, ZDVE=, ZDRO_i=, ZDRA_i=, ZDVE_i= (onset)
RAkA=, RAkP=, ROkA=, ROkP=, RAkA_i=, RAkP_i=, ROkA_i=, ROkP=i (harmonics)

TiRiFiC v. 2.1.5
Several bugfixes concerning radial and tangential harmonics (RAkA=, RAkP=, ROkA=, ROkP=, RAkA_i=, RAkP_i=, ROkA_i=, ROkP=i (harmonics)).

v2.2.0
TiRiFiC version 2.2.0 is available from here:
http://www.astron.nl/~jozsa/tirific/dow ... ation.html
The most important change is that I made TiRiFiC a standalone software, which does not require GIPSY any more (instead it now requires wcslib and libreadline, but those are nearly standard).
Details:
- Change to standalone version.
- Input is FITS format now, GIPSY is not used any more.
- TiRiFiC is a command-line tool and can be started calling a binary.
- Included parameter DEFFILE (specify name of default file).
- Included parameter PROMPT (switch interaction with the user on and off).
- Included parameter RESTARTNAME (specify a file, which, if changed, will cause TiRiFiC to run again without initialisation, useful for pipelines and frontends).
- Minor bugfixes.
Bug reports are welcome.
Next developments:
- fixing coolgal output.
- implementing models with fewer parameters (in collaboration with Milan den Heijer, AIfA).
- searching and implementing better minimisers (in collaboration with Milan den Heijer, AIfA).
- testing slightly modified goodness-of-fit evaluations.

TiRiFiC: v. 2.2.2
Minor bugfixes:
i) restart capability was broken for SuSE because of delayed read of files.
ii) more header items copied across to make a use of model and original data cube in kvis possible.

TiRiFiC v. 2.2.3
Minor bugfixes: i) Output deffile could not have the same name as input deffile.
New Feature: Made COOLGAL output fully functional, included COOLBIN parameter.
