ING Instrumentation Options


This page gives an overview of the instrumentation available at the WHT and INT. If you need more information about a given instrument, click on the instrument name, or email 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.

Note that as part of ongoing rationalisation of the WHT's instrument suite, and following consultation with the ING's observing communities, the adaptive-optics instruments (NAOMI/INGRID, NAOMI/OASIS) are not available after 31st January 2015, i.e. from 2015A onwards.

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 are given here; please email queries to the LIRIS MOS specialist Cecilia Fariña (cf@ing.iac.es). 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. AF2: improvements to the target-acquisition procedure and to the mapping of field distortion at WHT prime focus have improved the acquisition accuracy to better than 0.4 arcsec for 90% of fibres out to 20 arcmin from the center of the field of view (beyond this radius, there is significant vignetting). For reference, in seeing of 0.5 - 1.5 arcsec, a fibre-centring error of 0.4 arcsec leads to ~ 10% loss of light from a point source, relative to that from a well-centred fibre. Teams applying to use AF2 in 2014B are encouraged to check the latest AF2 news.
  4. 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.
  5. Visitor instruments: applicants wishing to submit proposals to use these 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.
  6. CCDs: specifications and technical details are given on the ING detectors page.
  7. Filters: details are given on the ING filters page.
