cds-question@unistra.frsurveysradio-sourcesWe describe the source subtraction strategy and observations for the extended Very Small Array (VSA), a cosmic microwave background interferometer operating at 33GHz. A total of 453 sources were monitored at 33GHz using a dedicated source subtraction baseline. 131 sources brighter than 20mJy were directly subtracted from the VSA visibility data. Some characteristics of the subtracted sources, such as spectra and variability, are discussed. The 33GHz source counts are estimated from a sample selected at 15GHz. The selection of VSA fields in order to avoid bright sources introduces a bias into the observed counts. This bias is corrected and the resulting source count is estimated to be complete in the flux-density range 20114mJy. The 33GHz source counts are used to calculate a correction to the VSA power spectrum for sources below the subtraction limit. Erratum: Table A1 of Cleary et al. (2005) was described as listing the 33-GHz sources used for the source-count estimation. However, an error was made in generating the text of Table A1. This erratum gives the correct source list used for the counts. This error does not affect any of the results of the paper, as the correct source list was used to estimate the counts. Of the 102 sources which were used to estimate the counts, 45 came from the VSA123 fields with 20mJy<=S< 46mJy and 57 came from the VSA5678 fields with 20mJy<=S< 114mJy. However, Table A1 of Cleary et al. (2005) omits (in error) nine sources from VSA123 with 35.9mJy<=S<46mJy and includes (in error) three sources from VSA5678 with S>114mJy. Also, for some sources the quoted uncertainty was a factor of sqrt(2) too large. Table 1 below lists the 102 sources used to estimate the 33-GHz source counts in Cleary et al. (2005). The normalizing area for the source counts is 0.044sr except for those sources brighter than 46mJy, for which it is 0.024sr. For each source, the measured flux density, S, and 1sigma uncertainty, {Delta}S, in mJy are presented. In addition to the quoted error, there is a calibration uncertainty of ~4 per cent in flux density.2005MNRAS.360..340Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/360/340CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/341/1066 : Very Small Array.
