Estimation of Galactic Model Parameters In High Latitude With SDSS and SCUSS

Using star counts method, we estimated the Galactic structure parameters in high latitude field (50° <= l <= 55°, -46° <= b <= -44°), 10 deg² field with Sloan Digital Sky Survey (SDSS) and South Galactic Cap of U-band Sky Survey (SCUSS), to explore their possible variations with absolute magnitude. Here we just considered three components: double exponential thin disk and thick disk and a de Vaucouleurs halo. And these parameters were obtained by minimising χ².
