PI/CoI Name: (no punctuation; separate with spaces) Matches all words. Write !word to reject results that contain it
Program Title: (no punctuation; separate with spaces) Text search the program Title. Matches all words. Write !word to reject results that contain it
Publication: (bibliography code of related publication) Search for data related to a publication by it's bibliography code.
Target Name: (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.
Resolver: SIMBAD NED VIZIER Resolve (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.
RA: (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.
Dec: ([+-]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.
Search radius: (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.

This option will be removed soon, in favor of the Processing State, combined with observation type or other selection criteria as appropriate.
Filename Prefix: (help) Specify the first part of the filename to match by.
Exclude Find Only Site Monitoring Data (help) Choose whether to include, or exclude site monitoring data.

Program ID: (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
Date: UTC Night (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.

Mode: Any Imaging Spectroscopy Long-slit spectroscopy Multi-object spectroscopy Integral field spectroscopy (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.

Central Wavelength: (microns, eg 1.2 or 2.0-2.4) Central Wavelength in microns. The valid range is 0.2-30 microns. You can supply a single value or a range. If you use a single value, we assume a range of +-0.1. Note this just searches for files where the central wavelength of a spectrum is within the given range, or within 0.1 microns of the given value. It does not currently know the spectral range of the data and check if the value given is within that range. Note also that central wavelength isn't a very useful concept with some configurations - in particulr we do not recommend searching on central wavelength for GNIRS XD data.

Adaptive Optics: Any Not AO AO NGS LGS (help) Select data did or did not use Adaptive Optics, or that used specifically LGS or NGS AO.
Processing: Any Raw Data Science Quality Quick Look (Processing status of data) Select here if you would like to search for raw data or a specific type of reduced data. Science Quality data are intended to be suitable for science use, however in most cases they have been generated automatically and have not been reviewed by an expert. There will likely be cases where the automatic reduction does not provide good results and the onus is on the end user to verify that the data and reduction meets their requirements. See here for details.
Processing Tag: Default (Processing Tag) Reduced data in the archive is tagged by processing batch. Select here if you would like to search for a particular set of reduced data. This list populates from the current search results.
