News about Science Data Product Forum
We would like to draw your attention about the existence of the Science Data Products internet forum which can be found at: http://www.eso.org/sci/data-processing/forum.htmlHAWK-I News
On this page, we list the main changes that affected the instrument and this web site.
- May 29, 2009: To be consistent with all VLT instruments, HAWKI has now a different offset scheme. Read carefully the P84 User Manual
- May 07, 2009: A few parameters controlling the readout mode of the instrument were changed. These parameters improve the ringing seen when observing bright sources. The parameters that have been changed are stored in the headers of the images and can be used to distinguish the mode used for a given file. These parameters are DET.RSPEED changed from 6 to 8 (effectively increasing the minimum DIT from 1.3 to 1.6; DET.VOLT1.DC6 was changed from 2.4 to 2.1 Volts; and DET.VOLT1.DC7 was changed from 3.4 to 3.6 Volts. This change take effect starting the night of 2009-04-07.
- Jan 31, 2009: The January intervention was successfull, and the thermal background is now three times lower.
- 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.
- July 11, 2008: HAWK-I entrance window damage giving troubles for sky subtraction. See this report.
- August 22, 2007: HAWK-I takes off (ESO press release)
- August 2007: Call for proposal for Science Verification
