J/MNRAS/301/203     408-MHz variability study              (Riley+ 1998)

A 408-MHz variability study of two fields in the region 06:30 +45° Riley J.M., Green D.A. <Mon. Not. R. Astron. Soc. 301, 203 (1998)> =1998MNRAS.301..203R
ADC_Keywords: Radio sources Keywords: catalogues - surveys - radio continuum: general Abstract: Variability in 408MHz flux density, over a 1yr interval between 1995 and 1996, has been investigated using the DRAO Synthesis Telescope for a complete sample of 322 sources with S(408MHz)>80mJy at galactic b=15°; four sources are found to show significant flux density variations.
