CARMA Project Database Search

This page provides quick ways to handle the most common types of searches you will use to locate and retrieve your data.
Tracks Transferred in the last 2 Days
Project Search
Returns a list of projects given a project ID and investigator.

Note: In general, if you know the project ID, it is normally a good idea to specify only the project ID and not the investigator.

Project ID (e.g., c0001)

Principal Investigator

Obsblock (Trial) Search
Returns a list of trials given an observing block ID, and/or date or date range.

Note: In general, if you know the obsblock ID, it is normally a good idea to specify only the obsblock ID and not the date.

Obsblock ID (e.g., n604_coD)

Source Coordinate Search - Rectangular Regions
Coordinate searches are possible over rectangular regions on the sky defined by a bottom left corner and top right corner, both specified in right ascension and declination in J2000 equinox only. Supported text entry formats for right ascension and declination are illustrated adjacent to the entry fields below.

Bottom Left Corner RA (J2000) (e.g., 02h08m34.5s, 02:08:34.5, or 02 08 34.5)
Bottom Left Corner DEC (J2000) (e.g., 00d02m33.4s, 00:02:33.4, or 00 02 33.4)
Top Right Corner RA (J2000) (e.g., 03h08m34.5s, 03:08:34.5, or 03 08 34.5)
Top Right Corner DEC (J2000) (e.g., 03d02m33.4s, 03:02:33.4, or 03 02 33.4)

Source Coordinate Search - Square Regions
Coordinate searches are possible over square regions on the sky defined by a center point and width, both specified in right ascension and declination in J2000 equinox only. Supported text entry formats for right ascension and declination are illustrated adjacent to the entry fields below.

Center RA (J2000) (e.g., 09h08m34.5s, 09:08:34.5, or 09 08 34.5)
Center DEC (J2000) (e.g., 15d02m33.4s, 15:02:33.4, or 15 02 33.4)
Width (Arcminutes, e.g., 1.2)

Explanation of Terms

Project ID
The project identification number, also the first five characters in the file name (e.g. c0001, in c0001.n604_coC.1.miriad.tar.gz).
Investigator
The name of a single investigator. The format is FIRSTNAME LASTNAME. For example "John Smith" will have the desired effect. We have investigator information only for proposals which have been refereed starting around project c0001. Thus, we have investigator information for projects such as c000*, cx*, cs*, but not ct* or older projects.
Observing Block ID
The ID of the observing block (e.g., n604_coC).
Date Range
Date range (inclusive) for which to search (e.g., 2007-05-07). Note the YYYY-MM-DD format. If only one value is specified, that date is searched for. The * wildcard character will not work.
