Abstract - download The instrument FRIDA (inFRared Imager and Dissector for Adaptive optics) is an integral field spectrograph (near infrared) with imaging capability for being used at the Nasmyth B platform of the Gran Telescopio de Canarias (GTC), behind the Adaptive Optic (AO) system. FRIDA is the first GTC instrument to use the telescope AO system. FRIDA is a collaborative project between institutions from México, Spain and the USA. In image mode, FRIDA provides scales of 0.010, 0.020 and 0.040 arcsec/pixel and, in integral-field spectroscopy (IFS) mode, spectral resolutions R 1000, 4.500 and 30.000. FRIDA has a set of different mechanisms (such as the focal plane wheel, the filters and pupil wheels, the cameras wheel, the calibration unit, the grating carousel) that are controlled and coordinated by the FRIDA Instrument Library (IL). In this paper, we present the IL, which provides the implementation of a Device that represents the instrument FRIDA as a whole. More specifically, the IL implements the commands for setting-up and coordinating the different mechanisms of FRIDA for an observation. It moves the mechanisms, exposes the detector, and reduces and stores the data image. In addition, we also present the Observation Manager (OM) component, responsible for the execution of the science observing sequences in close coordination with the IL and GTC AO system.
