HARPS News Updates
On this page, we list the main changes that affected the instrument and this web site. More News and Information can be found in the Science information pages
- IMPORTANT - Mar 22, 2020. Due to the COVID-19 pandemia, HARPS was warmed up and is temporarily out of operations. Once back, please bear in mind that you will have to apply an RV offset in your analysis if you combine data taken before 2020-Mar-22 and after that date.
- Mar 11, 2020: the problem regarding lower flux in the calibration fiber at high airmasses has been fixed.
- Mar 3, 2020: simultaneous FP and ThAr flux lower at high airmasses. We have noticed that the HARPS calibration fiber exhibits less flux when the telescope is very inclined (high airmasses). We are investigating the cause of the technical problem.
- Nov 28, 2019: The HARPS telescope adapter was decommissioned and replaced by the NIRPS Front End to allow simultaneous operations of HARPS+NIRPS. This change has no effect on the RV precision and has not introduced any RV offset.
- Oct 12, 2019: P2 is online (https://www.eso.org/p2ls/). Please use P2 to create your OBs.
==> If you wish to grant access to your OBs to an observer, please login into your ESO account via the ESO User Portal. There, click on 'Delegate Phase 2 tasks'. Select the run you wish to delegate, enter the email address of the ESO account associated with the observer and tick 'Phase 2'. Now the observer will be able to see, edit and execute the OBs of your run from the ESO account associated with her/him. Please note that delegating your run to another person / ESO account will not change the ID of your observing run.
- IMPORTANT - Sep 27, 2019: P2PP goes P2. Please note that due to a software upgrade on La Silla on Oct 12, 2019, P2PP will cease to work. For all observing runs after Oct 12, 2019, please use the web-based La Silla P2 tool (https://www.eso.org/p2ls/) to prepare the observations. Your OBs are then automatically transferred to La Silla; no need to ftp them anymore.
- Sep 27, 2019: Pipeline problems affecting data taken with the Fabry Perot in the time frame 02-Feb-2019 to 16-Apr-2019 - DONE. Due to a problem in the HARPS pipeline recipe the Fabry Perot calibration files after 01-Feb-2019 were not copied into the calibration database, and therefore the reference Fabry Perot spectrum was not updated. For this reason, all night-time science data taken with the Fabry Perot in the time frame 02-Feb-2019 to 16-Apr-2019 at 13:14 UT were reprocessed with the correct calibration files and are available in the archive.
- November 15, 2018: The Laser Frequency Comb (LFC) is now running at HARPS. It is used for calibrations only and is not offered for night-time observations.
- February 23, 2016: A Messenger article describing the May 2015 upgrade to the fiber-link is available in the December issue.
- August 1, 2015: A letter has been sent to all HARPS Programme PI about the upgrade mentioned earlier and is also available here.
- July 4, 2015: The HARPS polarimeter has now been realigned and the flux on both fibres is now within 30% (fibre B being less efficient).
- June 3, 2015: After 12 years of operations a new fiber-link has been installed on HARPS. This includes the EGGS mode, and the "sky fiber" of this mode is now available. Therefore starting from June 1st 2015 we expect a change in zero point in the determination of the radial velocities. We have collected the data to determine this offset as a function of stellar spectral type, and we are going to make the values available soon. We expect the effect of de-focussing and de-centering on the RV determination to be strongly reduced. The polarimetric mode of HARPS is not yet realigned with the new fibers and we measure a lower flux on fiber B by a factor 2 - 3. We intend to recover this as soon as possible. A full report will be made available to the community through these web pages and later through the ESO messenger.
