This development is applied in the case of color-color planes, defining what we call the proximity parameter, which is used for luminosity classification purposes and for an improved use of calibrations.4 p.application/pdfeng(c) The European Southern Observatory (ESO), 1992EstelsCinemàtica galàcticaEstadística matemàticaStarsGalactic kinematicsMathematical statisticsinfo:eu-repo/semantics/article0763862020-05-20info:eu-repo/semantics/openAccess
