Information on Service '2007-2010 ANTARES search for cosmic neutrino point sources'

[Use this service from your browser]

Further access options are discussed below

A time integrated search for point sources of cosmic neutrinos was performed using the data collected from January 2007 to November 2010 by the ANTARES neutrino telescope. This dataset includes a total of 3058 events obtained during the effective livetime of 813 days. This is legacy data. The most recently released data can be found at ivo://org.gavo.dc/antares/q/cone.

Service Documentation

This table can be used for TAP queries. To give you an idea of what you can do, there's an example in the TAP service.

A worked out use case on comparing IceCube and Antares data using TOPCAT was kindly contributed by Vladimir Kulikovsky.

Here is another sample query that gives, for all the areas of the neutrinos, the average energy and the number of photons per area from the ROSAT survey:

SELECT
        a.id,
        AVG(energy_cor) AS mean_energy,
        COUNT(*)/(ang_error*ang_error)/exposure_time
FROM antares10.data AS a
JOIN rosat.photons AS p on
1=CONTAINS(POINT('', p.raj2000, p.dej2000),origin_est)
GROUP BY a.id, ang_error

Note that since this has to do a linear scan through the relatively large ROSAT photon table, the query will take a while; you will need to execute it in async mode.

In a separate step, you could compute these averages for the entire table and see if some systematics show up.

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.

NameTable Head DescriptionUnitUCD
_r Dist. Distance to cone center deg pos.distance
ang_error Ang. Error 1 sigma confidence radius of the position. deg stat.error;pos
dej2000 Dec Declination, ICRS deg pos.eq.dec;meta.main

raj2000 RA Right Ascension, ICRS deg pos.eq.ra;meta.main

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.

NameTable Head DescriptionUnitUCD Verb. Level
id Id Identifier for this neutrino. N/A meta.id;meta.main 1
raj2000 RA Right Ascension, ICRS deg pos.eq.ra;meta.main 1
