Availability of VLA Measurements of M87?

-- | January 14, 2016

Question: I am contacting you on behalf of the MAGIC collaboration. I was wondering whether you took with VLA any further data on M87. We are trying to get an MWL coverage for our observation period spanning from 2012 to 2015. What we would need is the lightcurve for these years and a skymap. — Cornelia

Answer: In fact, you can search the VLA data archive, which contains all of the data acquired by the VLA since it started observations in 1976, for observations of M87. Go to https://archive.nrao.edu/archive/advquery.jsp to access the NRAO science data archive (which contains the VLA science data). You will need to generate the images from these measurements yourself, and also any lightcurve derived from these measurements.
