HAWK-I News

On this page, we list the main changes that affected the instrument and this web site.

• Nov 19, 2008: An intervention is planned for the beginning of January 2009 to investigate the thermal background increase.
• Sep 1, 2008: A new HAWK-I cooling mode has raised the thermal background of the instrument to approximately 2 e/s/pix (previously it was 0.1-0.2 e/s/pix). The only filters seriously affected are NB1060, and NB1190, which will need approximately 50% more integration time to reach same S/N for faint objects. The origin of this increased background is under investigation.
