修正的SWIRE测光红移
Revised SWIRE photometric redshifts
摘要：
我们已经修订了SWIRE测光红移星表，以考虑到SWIRE几个地区的新光学测光，并纳入2MASS和UKIDSS近红外数据。孔径匹配是结合近红外和光学数据的一个重要问题，我们已经探索了一些方法来做到这一点。增加的光度带的红移解决方案的结果在均方根误差的改善，特别是在离群率。我们还发现，将尘埃环发射到类星体模板提高类星体红移估计的性能。我们修订的红移目录包含超过100万个河外天体，其中26288个是类星体。
英文摘要：
We have revised the SWIRE Photometric Redshift Catalogue to take account of new optical photometry in several of the SWIRE areas, and incorporating 2MASS and UKIDSS near infrared data. Aperture matching is an important issue for combining near infrared and optical data, and we have explored a number of methods of doing this. The increased number of photometric bands available for the redshift solution results in improvements both in the rms error and, especially, in the outlier rate. We have also found that incorporating the dust torus emission into the QSO templates improves the performance for QSO redshift estimation. Our revised redshift catalogue contains over 1 million extragalactic objects, of which 26288 are QSOs.
