§ 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 the latest advice about any performance issues not addressed in 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.
