为了预测在任意波长和视星等极限下沿任意视线的红外恒星光度函数，发展了一个简单的星体和消光(尘埃)分布的指数圆盘模型。模型光度函数被用来确定恒星场对寻找II型OH脉泽的红外对应物的污染程度。模型参数使用文献中提供的2.2微米源计数数据和首次在此提供的新数据进行了校准。在平面上，在半径为20角秒的搜索区域内，磁场污染在2.2微米处为8级，在3.5微米处为7级。
A simple exponential disc model for the distribution of stars and extinction (dust) in the galaxy is developed for the purpose of predicting the infrared stellar luminosity function along an arbitrary line of sight at any given wavelength and apparent magnitude limit. The model luminosity function is used to determine the extent to which the stellar field will contaminate searches for the infrared counterpart of type II OH masers. The model parameters are calibrated using 2.2µm source count data available in the literature, and new data presented here for the first time. In the plane, contamination by the field is found to be serious by 8th magnitude at 2.2µm and 7th magnitude at 3.5µm for a 20 arcsec radius search area.
