Description of contents: This package is composed of four FITS files containing the same column descriptions for different peaked-spectrum and convex source
samples. 

  high_low_freq_peakedspectrum_table.fits lists the peaked-spectrum sources 
  in the high and low frequency samples (sources with a spectral peak between 72 MHz and 1.4 GHz).
  gps_sample_peakedspectrum_table.fits lists the sources from the GPS sample (sources that have a peak above 843 MHz). 
  convex_src_table.fits lists the convex sources outlined in the manuscript.
  srcs_peak_below72MHz.fits lists the sources that peak below 72 MHz.

System requirements: Any FITS reader.

Additional comments: The column headers for each FITS file is as follows:
