AIRY-LN: an ad-hoc numerical tool for deconvolution of images from the LBT instrument LINC-NIRVANA

LINC-NIRVANA (LN) is the German-Italian Fizeau beam combiner for the Large Binocular Telescope (LBT), composed of two 8.4-m apertures on a unique mount. It will provide multiple images of the same astrophysical target corresponding to different orientations of the 22.8-m maximum baseline. Starting from the already existing Sofware Package AIRY (a set of IDL-based modules developed within the CAOS "system" and dedicated to simulation and/or deconvolution of single or multiple images), an ad-hoc version has been especially designed for the data that will be obtained with LN. In this paper, we present the resulting Software Package AIRY-LN. Its capabilities, including quick-look methods, methods for specific classes of astronomical objects, PSF extraction, and a blind deconvolution algorithm are detailed. An IDL-licence-free (by means of the IDL Virtual Machine) and observer-oriented version of the whole package (with pre-setted LN image processing parameters) is also presented.
