Sample Catalog Search Parameters

Sample ID

The Sample ID number uniquely identifies each sample. Sample ID numbers are generally in the format AA-PPP-### where AA is something mysterious, PPP is the three letter principle investigator code, and ### is a serial number. This format is not structurally enforced by our database, however, and sample ID numbers can be any string of text. You may search for more than one Sample ID at a time by entering a comma delimited list of Sample IDs in the search field. Example:

AA-BBB-001,AA-BBB-002,AA-BBB-003

In Sample ID search, you can use the wildcard '_' to represent exactly one unknown character, or the wildcard '%' to represent zero or more unknown characters. So you could find all the samples in the above example, and possibly six others, with a search for

AA-BBB-00_

To get all the AA-BBB samples in the teens and thirties, you could search for

AA-BBB-01_, AA-BBB-03_

And if you want all the AA-BBB samples, then search for

AA-BBB-%

Relab File

The Relab File is a unique identifier for one measurement of a particular sample. If you search by Relab File, then your results will contain the sample which has a spectral measurement tagged by that Relab File ID. You may search for more than one Relab File ID at a time by entering a comma delimited list of Relab File IDs in the search field. Example: AAA001,AAA002,AAA003

Principle Investigator

The three-letter code for the name of the principle investigator

Sample Name

The name given to the sample. Sample naming conventions vary.

Planetary Origin

Planetary Origin is denoted by a two-letter code. Presently, there are only three possible planetary origins (though hopefully that will change soon). Terra is TE, Luna is LU, and everything else is XT (x-tra terrestrial).

Min Size

The minimum grain size in the sample.

Max Size

The maximum grain size in the sample.

Texture

The texture of the sample.

Origin

The origin of the sample.

Text

Descriptive text about the sample.

Wavelength Range

Will return samples that have spectral data that overlaps with your chosen wavelength range.

• Visible, Near-IR is 350 - 2400 nanometers
• Mid Infra-Red is 3000 - 25000 nanometers

Bulk Download Text Format

Bulk Download is available on the results page that lists all samples which matched your search criteria. Each sample on the list has a checkbox labelled BULK in it's leftmost column. If you click the Bulk Download button, then you will receive an XML formatted text file that will contain all of the information about every sample on the search results page for which the BULK checkbox is checked. At this time, the XML file is well-formed but not valid, which means that it is legitimate XML but does not have a document type definition. There is currently no XML standard for expressing spectral data, but there are standards in the works and we hope to be able to conform to a standard when it emerges. In the meantime, the XML file produced by this website is both human and machine readable, and is easy to parse and understand. At the time of this writing, the only browser that will display XML is Microsoft Internet Explorer 5.0.
