LINC-NIRVANA observation preparation software: a flexible approach

LINC-NIRVANA (LN) is a near-infrared imaging interferometer for the Large Binocular Telescope (LBT). It is expected to have unprecedented imaging performance in the near-infrared both in terms of angular resolution and limiting magnitude, thanks to the large collecting area of the two LBT mirrors (8.4m) and by means of Multi-Conjugated Adaptive Optics (MCAO) and a Fringe and Flexure Tracker System (FFTS). For such a complex instrument the process of observations has to be carefully prepared, considering the constraints imposed by features of the instrument and scientific objectives. This paper addresses the design of the LN Observation Preparation Software (LOPS), the main goal of which is to provide the observer with a tool to create valid observation program for LINC-NIRVANA. The current status of LOPS with its key components is described and critical aspects are addressed
