Overview of Instrumentation at ING


This page gives an overview of the instrumentation available at the WHT and INT. Further information about a given instrument can be obtained by clicking on the instrument name, or by emailing one of the listed instrument specialists.

Notes (§) about specific instruments and procedures can be found at the bottom of the page.

Information about applying for telescope time can be found on a separate page.

The instrument suite at ING is evolving (latest news here), in preparation for the deployment of new survey instruments on both telescopes (and following a 2014 poll of the community). The key points for prospective users of the WHT during and after 2019A are:

  1. Visiting Nasmyth instruments will use the GRACE Nasmyth platform (rather than GHRIL).
  2. It's envisaged that ISIS, LIRIS and ACAM will continue to be available during the era of the WEAVE surveys (from late 2019).

Information about instruments no longer offered at ING (e.g. the multi-object spectrograph AF2) can be found on a separate page.

SIGNAL can be used to calculate exposure times for most telescope/instrument/detector combinations.

§ Notes

  1. LIRIS: slit-mask preparation and manufacture takes approximately eleven weeks; PIs awarded time in multi-slit mode are strongly encouraged to initiate the design of slit masks at the earliest opportunity. Information about slit-mask design and timelines is given here. As of semester 2014B, the cost of manufacturing the slit masks (600 - 900 euros per mask) must be covered by the home institution of the proposing team.
  2. ACAM: observations can be made at any time, except when an instrument is mounted at WHT prime focus.
  3. INT WFC: offered at rotator angle 180 degrees only. When there is compelling scientific justification, other rotator angles (0, 90 or 270-degrees) can be offered for the duration of the run; changes to the rotator angle within a run are not permitted.
  4. Visitor instruments: the list in the table above includes those instruments whose teams have expressed an interest in collaborative proposals. Prospective applicants should in the first instance contact the relevant person named in the above table. Applicants wishing to submit a proposal based on a new (to ING) visitor instrument should follow these instructions. After 2016B, visiting instruments requiring a Nasmyth focus have been hosted on the GRACE Nasmyth platform (rather than GHRIL).
  5. CCDs: specifications and technical details are given on the ING detectors page.
  6. Filters: details are given on the ING filters page.
  7. Spectroscopic resolutions quoted for ISIS, LIRIS, ACAM and IDS assume a 1-arcsec slit.
  8. PAUCam was successfully commissioned at WHT prime focus in 2016. Observers interested in using PAUCam should contact Francisco Castander at the email address above, for advice about any technical issues not covered on the PAUCam web pages, and also for advice about the likely timing of PAUCam survey runs during the coming semester. All scheduled observations will be carried out by the PAUCam team.
