Release 2.3.1 of MiRA

This version has been modified for better integration in the OI-Imaging framework.

Release 2.0.0 of MiRA

This major release provides the following features:

• Accounting of spectral bandwidth smearing (with customizable shape and importance factor).
• Plugins can be loaded by MiRA to modify the model of the complex visibilities. See file mira2_plugin_central_star.i for a concrete example or have a look at SPARCO plugin.
• Can save model complex visibilities (options -save_visibilities).
• Add soft-thresholding (skip thresholding if no pixels above soft-threshold level).
• Add multi-thread support.
• Use environment variables MIRA_SRCDIR and MIRA_YORICK.
• 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.

Beta version of MiRA 2

MiRA-2 is an almost complete rewrite of MiRA-1 with the objective to support 2nd generation VLTI instruments. For the end user the most significant changes are:

• Accounting of bandwidth smearing (with customizable shape and importance factor).
• Ability to save model complex visibilities (options --save_visibilities).
• Multiple possible choices for the objective function used for specific kind of (partial) data. The various objective functions follow the equations in published papers.
• Improved accounting of missing/partial data.
• Optional recentering and/or soft-thresholding of the input image.
• Multi-thread support.
• Environment variables MIRA_SRCDIR and MIRA_YORICK can be used to specify where are installed the sources and wich Yorick interpreter to use.

MiRA-2 is intended to be used form the command line, the result being saved to a FITS file. Graphics display has been removed (could be back later).

MiRA version 1.1.2

Changes:

• Fix accounting of bad data in OI-FITS file.
• Ability to resample images.
• Improve graphics.
• Fix multiple wavelenghts case.

MiRA version 1.1.1

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

MiRA version 1.1.0

• 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.
