我们从A262、巨蟹座、A1367、A1656（彗发）、A2147、A2151（大力神）和飞马座等7个星团中提取了200多个星系的远红外特性。红外选择的样本几乎全部由红外正常星系组成，其Log L(FIR) = 9.79太阳光度，Log L(FIR)/L(B) = 0.79, Log S（100微米）/S（60微米）= 0.42。没有一个样本星系的Log of L（FIR）大于11.0太阳光度，只有一个样本星系的FIR- blue光度比大于10。在hi -缺陷星系团和hi -正常星系团的FIR性质上没有发现显著差异。参考文献33篇。
Far-infrared properties are derived for a sample of over 200 galaxies in seven clusters: A262, Cancer, A1367, A1656 (Coma), A2147, A2151 (Hercules), and Pegasus. The IR-selected sample consists almost entirely of IR normal galaxies, with Log of L(FIR) = 9.79 solar luminosities, Log of L(FIR)/L(B) = 0.79, and Log of S(100 microns)/S(60 microns) = 0.42. None of the sample galaxies has Log of L(FIR) greater than 11.0 solar luminosities, and only one has a FIR-to-blue luminosity ratio greater than 10. No significant differences are found in the FIR properties of HI-deficient and HI-normal cluster galaxies. 33 references.
