摘要：
We investigated the luminosity function LF and initial mass function IMF of open star cluster Collinder 70. The classical definition of van Rhijn (1936) has been followed in calculating the LF. Statistical investigation of the dispersion around a range of magnitudes concerning what is called Wielen dip revealed that the dip is unreal. Confirming the unreality of that dip, we computed the IMF of Collinder 70; the statistical study of IMF confirmed the results that obtained by using LF, i.e.. there is no dip for Collinder 70.
