我们提出了90妈妈光度功能的欧洲大面积ISO调查（ELAIS）的最终分析，我们以前的分析（论文IV）的样本量扩展约4倍。我们的样品延伸到z = 1.1，类似于论文IV的50倍共动体积，和10（7.7）70 mJ y），我们获得了61%的样品的红移（151个红移），在7 μ m，15 μ m，20 cm或明亮的（B <18.5）光学识别处识别到B <21。选择功能是定义良好的，允许建设的最终分析目录在ELAIS北方领域，这是在很好的协议与我们的初步分析光度功能在ELAIS S 1领域从文件IV的90妈妈光度功能。光度函数也与Serjeant和Harrison最近基于IRAS的预测非常一致，如果正确的话，需要（1 + z）（3.4 +/- 1.0）的光度演化与源计数保持一致。这意味着在共动体积平均星星的形成率在z小于或接近1的演变与来自静止帧光学和紫外线调查。
We present the 90-mum luminosity function of the Final Analysis of the European Large Area ISO Survey (ELAIS), extending the sample size of our previous analysis (Paper IV) by about a factor of 4. Our sample extends to z = 1.1, similar to50 times the comoving volume of Paper IV, and 10(7.7) 70 mJy), we obtained redshifts for 61 per cent of the sample (151 redshifts) to B <21 identified at 7 mum, 15 mum, 20 cm or with bright (B <18.5) optical identifications. The selection function is well-defined, permitting the construction of the 90-mum luminosity function of the Final Analysis catalogue in the ELAIS northern fields, which is in excellent agreement with our Preliminary Analysis luminosity function in the ELAIS S 1 field from Paper IV. The luminosity function is also in good agreement with the recent IRAS-based prediction of Serjeant and Harrison - which, if correct, requires luminosity evolution of (1 + z)(3.4 +/- 1.0) for consistency with the source counts. This implies an evolution in comoving-volume-averaged star formation rate at z less than or similar to 1 consistent with that derived from rest-frame optical and ultraviolet surveys.
