Hello, everybody. I'm conducting an investigation in planetary sciences. Specifically in exoplanet detection by the radial velocity method and I'm stuck because I need to know how to defend the data that I'm using. I'm using the data from http://exoplanet.eu/catalog/ and I have found some data with errors in the mass about 300%!!!!! In astronomical researchs, what are the typical uncertainties (errors) permitted? and, what articles or books can I read in order to get arguments for defending my investigation with those data? Thanks for your help.
