OCRA-p observations of the CRATES sources at 30 GHz

This page provides the spectra and variability plots for the CRATES sources observed with OCRA-p (Peel et al. 2011), as well as a machine-readable copy of the source list. The abstract for the paper reads:

The reference for the paper is:

Wilkinson (2011), "OCRA-p observations of the CRATES sources at 30 GHz", MNRAS, 410, 2690, arXiv:1007.5242v1 [astro-ph.CO]

Plots of the source spectra, and for the 30 GHz flux density of the source over time, are given below. Axis labels are not included in the figures. For the spectral plots, the X-axis is frequency (in GHz), and the Y-axis is flux density (in Jy). For the variability plots, the X-axis is time (in modified Julian date) and the Y-axis is flux density (in mJy). You can also view all of the spectral plots on one page, and also the variability plots all on one page.

A machine-readable copy of the flux densities of the sources at 1.4, 4.8, 8.4 and 30 GHz is available here (UPDATED January 2010 - correcting a ~1% error in the calibration, and the application of the gain-elevation curve, as per the erratum - see page 20 of the preprint on arXiv). There is also a version that includes some notes on the sources (see section 4 of the paper for a description of these). The catalogue is also available for browsing on HEASARC.
