(no punctuation; separate with spaces) Matches all words. Write !word to reject results that contain it
(no punctuation; separate with spaces) Text search the program Title. Matches all words. Write !word to reject results that contain it
(bibliography code of related publication) Search for data related to a publication by it's bibliography code.
(Name of Target) Enter a target name here. If you don't Resolve the target name into a co-ordinate search, this will do a search on the target name as specified in the phase-II. Be aware that observers sometimes use a different target name to what you expect - this is only really useful if you set up the Phase-II, or otherwise know exactly what target name was used. If you set a Name Resolver and click resolve, we will fetch co-ordinates of your target from the resolver specified and then the search will disregard the target name and search only by co-ordinates. Note that the name resolvers will not work solar system bodies.

Searches on the target name are not case sensitive, and you can use the * character as a wildcard - for example mrk* will find e.g. Mrk42, and *io* will find e.g. Io, Io.eph, Orion, etc.

(Name Resolver) Choose a Name Resolver and click the resolve button to attempt to find the co-ordinates of your named source. If the form has both a target name and co-ordinates, the search will disregard the target name. Note: The name resolvers will only work for objects outside the solar system, there's no capability for meaningful use with moving objects, for example planets.
(HH:MM:SS.ss or decimal degrees) Right Ascension. You can use HH:MM:SS[.ss...] or decimal degrees. In either case you can specify a single value or a range, eg 11:22:33 - 12:34:56. If you enter a single value, also see the Search Radius field.
([+-]DD:MM:SS.ss or decimal degrees) Declination. You can use [+|-]DD:MM:SS[.ss...] or decimal degrees. In either case you can specify a single value or a range, eg 11:22:33 - 12:34:56 or -65:43:21 - -12:34:56. If you enter a single value, also see the Search Radius field.
(arcsecs or decimal degrees) Search radius in arcseconds, unless you specify "d" or "degs" to make it decimal degrees. i.e. 180 means 180 arcseconds, 10degs or 10d means 10 degrees.
If RA and/or dec has been given as a single value (as opposed to a range), this specifies the size of the box around it to search. This is actually a simple search in a square box (in the tangent plane), not a true cone search. Strange things may happen near the poles.

(click to show / hide) Click where it says "Advanced Options" to show or hide the advanced options. (click to show / hide) Click where it says "Column Selection" to show or hide the panel that lets you choose the columns to be shown in the results. You need to click on 'Search' to apply the changes
(or Obs. ID / Data Label. Exact Match) You can put a program ID, Observation ID or Data Label into this box. The search will be for an exact match to what you put in, substring type matches are not provided. Example: GN-2001A-Q-1
(YYYYMMDD or start - end) You can specify 1) an individual date in the form YYYYMMDD, 2) a date range in the form yyyymmdd-YYYYMMDD, or 3) a date-time range in the form yyyymmddThhmmss[.s...]-YYYYMMDDTHHMMSS[.S...]. Examples: 20101231 or 20100101 - 20100131 or 20101122T012345-20101231T231234. You can also specify whether to search strictly on UTC date (note tha Gemini South observing nights span two UTC dates) or on Observing Night, which will use the traditional Gemini scheme of labelling observing nights by the UTC date at the start of the night with a 1400 (+- daylight savings in Chile) local time date rollover.
(Select GMOS for GMOS-N and GMOS-S) Select the instrument you are looking for data from.
(help) Select an Observation Class here, or set it to Any to not search by Observation Class.
(help) Select an Observation Type here, or set it to Any to not search by Observation Type.
(Imaging / Spectroscopy etc) Select Imaging or various Spectroscopy modes here. Spectroscopy implies all spectroscopic modes. Note that not all instruments support all these modes, such searches will return no results.
(help) Select data did or did not use Adaptive Optics, or that used specifically LGS or NGS AO.
(Processing status of data) Reduced data in the archive can have different reduction status. Select here if you would like to search for a particular type or reduced data, or for raw data only.

Finding Associated Calibrations... This can take several seconds depending on the size of your calibration association search...

You cannot do calibration association on an unconstrained search, or one that hits the search limit. Please revise your original search so that this is not the case.
