Service Documentation

This data set contains 28493 high-energy cosmic ray events recorded by the Pierre Auger Telescope (Mendoza/Argentina) recorded since 2004. The number of events in this sample corresponds to 1% of the total number of events.

Details about this data set are documented at http://www.auger.org/education/GAP2012_137.pdf.

Included are the event ID, the number of stations which participated in the event, the right ascension and the declination of the incident cosmic rays in degrees, the reconstructed energy of the event, the Modified Julian Day (MJD), and the galactic longitude and latitude.

All public Auger events can also be browsed via a web interface at http://auger.colostate.edu/ED/.

Overview

You can access this service using:

This service is published as follows:

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD

hscs_pos Position/Name Coordinates (as h m s, d m s or decimal degrees), or SIMBAD-resolvable object N/A N/A
hscs_sr Search radius Search radius in arcminutes N/A N/A
MAXREC Match limit Maximum number of records returned. Pass 0 to retrieve service parameters. N/A N/A

VERB Verbosity Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns. N/A N/A

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
