The first problem is to determine the rotation paramenter: we can observe only the velocity rotation projected along the line of sight. I determined this parameter via statistic analysis, collecting the data from literature … cubed itemsNettet19. mar. 2001 · The shape of the line-of-sight velocity distribution (LOSVD) is measured for a sample of 14 elliptical galaxies, predominantly low-luminosity ellipticals. The sample is dominated by galaxies in the Virgo cluster but also contains ellipticals in nearby groups and low density environments. The parameterization of the LOSVD due to Gerhard and van … cubed lineNettetRadial velocity. The component of velocity along the line of sight to the observer. Objects with a negative radial velocity are travelling towards the observer whereas those with a positive radial velocity are moving away.
