Information on Service 'Browser interface to VLBI images of Lockman Hole radio sources'

[Use this service from your browser]

Further access options are discussed below

These are 1.4GHz Very Long Baseline Interferometry images of 532 radio sources with a flux density exceeding 100uJy as determined by Ibar et al. (2009, MNRAS, 397, 281), obtained between 2010-06-03 and 2010-09-03. For all fields, we give frames processed using natural weighting to preserve maximal sensitivity. For the 65 detected sources, we additionally give frames processed using uniform weighting to suppress sidelobes (see Middelberg et al. 2013, A&A 551, 97 for details) in flux density measurements. Some sources have larger images to cover a larger area because the initial coordinates were not sufficiently accurate.

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.

NameTable Head DescriptionUnitUCD Verb. Level
