ADC_Keywords: Photometry, infrared ; Effective temperatures ; Stars, diameters Keywords: stars: fundamental parameters - stars: late-type - stars: sub-dwarfs - infrared: stars - techniques: photometric - methods: analytical Abstract: This paper presents a method to determine effective temperatures, angular semi-diameters and bolometric corrections for population I and II FGK type stars based on V and 2MASS IR photometry. Accurate calibration is accomplished by using a sample of solar analogues, whose average temperature is assumed to be equal to the solar effective temperature of 5777K.
