History of MiRA

Version 2.0.0a (2018-02-12)

Accounting of bandwidth smearing (with customizable shape and importance factor).
Improved accounting of missing/partial data.
Multiple possible choices for the objective function used for specific kind of (partial) data.
Speedup building of non-separable linear model (with or without smearing).
Global setting of the debug and quiet modes.
Colored messages.

Version 1.1.1 (2017-01-26)

Better algorithm to compute the dirty map and the dirty beam.
Improve command line help, provide a manual page.
Speed up plots.

Version 1.1.0 (2017-01-10)

Provide a command line interface (options in command line have units).
Provide configuration and installation scripts.
Now available on GitHub (https://github.com/emmt/MiRA).
Use Git submodules (see https://chrisjean.com/git-submodules-adding-using-removing-and-updating/ for a tutorial) for YLib, YOIFITS, IPY to share files with other repositories.

2008-10-03:

MIRA 0.9.5 released.
Fix bug when no target is specified in mira_add_oidata.
In mira_add_oidata/mira_new, keyword cleanup_bad_data can be set to 0, 1, 2 to achieve different levels of filtering of invalid data.
Various fixes in oifits.i for creating/saving OI-FITS files (thanks to Sylvestre Lacour).

2008-09-26:

MIRA 0.9.4 released.
Added the possibility to select the target in mira_new.
Hack for FLAG column to deal with AMBER data.

2008-09-23:

MIRA 0.9.3 released.
Fixed a bug in __mira_build_coordinate_list__ which prevent to use data files with central frequency (0,0) measured.
New function mira_dirac.

2008-09-07:

Massive rewrite of oifits.i to optimize the code, make it easier to read and let the users create OI-FITS data on the fly and save it to a file.

2008-09-04:

MIRA 0.9.2 released. This is the version used for the MIRA demonstration (see mira-demo.i) at SPIE 2008 Conference in Marseille (France).
Some change in plots.

2008-07-12:

MIRA 0.9.1 released. This is the version used for the VLTI 2008 Summer School at Keszthely (Hungary).
Missing fft_utils.i is now part of the distribution.

2008-06-06:

MIRA 0.9 released.

2008-05-02:

MIRA 0.8 released.

2008-01-31:

MIRA 0.7 released.
Orientation of u-v and image coordinates fixed to match astronmical conventions.
Use OptimPack1.
Noisy works again.
New Monte-Carlo optimizer.
Fix a bug in mira_add_oidata with loading of complex visibilities.

2007:

Penalty with respect to data is now computed for cartesian representation of a complex (not a polar).
Huge rewrite of code: all data of given type are collected in a single table (more compact representation and faster computation/plotting when a lot of interferometric data-blocks are fitted).
Wavelength selection is more flexible (you can specify the effective wavelength and bandwidth to consider).
Very fast approximation of the Fourier transform by means of FFT (or FFTW) and spectral interpolation.
