Comparison with MIRLIN and OSCIR |
The following table compares the capabilities of the three mid-infrared instruments available on the Keck telescopes. The OSCIR and MIRLIN performance characteristics were kindly provided to us by Andrea Ghez based on her analysis of observations made with both instruments by several science teams.
