OSIRIS is the optical Day One instrument, and so far the only Spanish
instrument, currently operating at the GTC. Building and testing an
instrument for a 8-10m-class telescope with nonprevious commissioning in
turn, has represented a truly unique experience. In this contribution,
the current status, the last commissioning results and some future
prospects are given.
This work is based on data of NGC1316 from the Very Large Telescope
(VLT). We used B, V and I-band observations obtained with the FORS1
Imager at ESO’s VLT in Paranal (Program 64.H-0624(A), P.I. M. Della
Valle).
The data reduction was carried out with the VST-Tube imaging pipeline. VST-Tube is a very versatile software for astronomical data analysis,
tested against imaging data taken with different telescopes/detectors,
adaptable to existing or future multi-CCD cameras
