得到了邻近富星系团A2199中心区域一个Abell半径范围内的312颗成员星系在B、V、R三个波段的光度函数,并且分别用Schechter函数和Gaussian函数及其组合进行了拟合。将所得到的光度函数与其它星系团以及场星系的光度函数进行了比较,发现与以前研究的星系团的光度函数并不一致,而与场星系的光度函数不存在明显差别。
We have derived the luminosity functions (LFs) of 312 member galaxies of one Abell radius in the central region of the nearby rich cluster of galaxies A2199 in the B, V and R bands. The Schechter function, Gaussian function and the combinations are used in our analyses. We compare our LFs with those for member galaxies in other clusters and that for field galaxies. Our LF is found to be inconsistent with previous studies of the cluster luminosity function, and not significantly different from the LF of field galaxies.
