Table information for 'vlastripe82.stripe82'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

This is a high-resolution radio survey of the Sloan Digital Sky Survey (SDSS) Southern Equatorial Stripe, a.k.a. Stripe 82. This 1.4 GHz survey was conducted with the Very Large Array (VLA) primarily in the A-configuration, with supplemental B-configuration data to increase sensitivity to extended structure. The survey has an angular resolution of 1.''8 and achieves a median rms noise of 52 μJy per beam over 92 deg^2. The catalog contains 17,969 isolated radio components, for an overall source density of ∼195 sources/deg^2. See also J.A. Hodge et al, 2011AJ....142....3H .

Columns

Sorted alphabetically. [Sort by DB column index]

NameTable Head DescriptionUnitUCD
c_sdss Cls SDSS morphological class of the closest match in SDSS DR6; s = stellar, g = nonstellar/galaxy. N/A src.morph.type
ct # Row count; this is not part of the original table but was added to satisfy SCS requirements. N/A meta.id;meta.main
d_sdss d(SDSS) Separation of the closest match in SDSS DR6. deg pos.angDistance
dej2000 Dec Declination, J2000 [Note p] deg pos.eq.dec;meta.main
f_int Int. flux Integrated flux density in mJy derived from the elliptical Gaussian model fit. [Note f] mJy phot.flux.density;em.radio.1500-3000MHz
f_peak Peak Flux Peak flux density derived by fitting an elliptical Gaussian model to the source. The uncertainty is given in the rms_nose column. mJy/beam phot.flux.density;em.radio.1500-3000MHz;stat.max
field Field The field name is the name of the coadded image containing the source. Note that the field name encodes the center of the field; field hhmmm+ddmmm is centered at RA = hh mm.m, Dec = +dd mm.m. The letter appended to the field name indicates the last catalog release in which the image was modified. N/A meta.id;obs.field
imag m_i SDSS i-band magnitude of the closest match in SDSS DR6. mag phot.mag;em.opt.I
n_sdss |SDSS| Number of matching SDSS DR6 objects within 8 arcsec. N/A meta.number
p_s P(S) Probability that the source is spurious (e.g., because of a sidelobe of a nearby bright source). [Note s] N/A stat.likelihood;obs
pa PA Position angle of the elliptical Gaussian model for the source after beam deconvolution, east of north. deg pos.posAng;meta.modelled

raj2000 RA Right Ascension, J2000 [Note p] deg pos.eq.ra;meta.main
rms_noise RMS noise Local noise estimate at the source position, calculated by combining the measured noise from all grid images contributing to the coadded map at the source position. mJy stat.error;phot.flux.density
smaj_ax Semimajor FWHM semimajor axis of the elliptical Gaussian model for the source after beam deconvolution. This is zero when the fitted value prior to deconvolution to is smaller than the beam (1.8'') due to noise. deg phys.angSize.smajAxis;meta.modelled
