DEIMOS Spectroscopic observations of MS0451-03

The tar file contains extracted spectroscopic observations of galaxies in the field of MS 0451-03 galaxy cluster. The observations were obtained with the DEIMOS instrument on the Keck Observatory. Details of the observations are given in Crawford et al., 2011, ApJ, 741, 98, DOI: 10.1088/0004-637X/741/2/98. The catalogs associated with that paper also have further information about these objects. The following files are included: 1. w05.m*-crawford.fits: A catalog for each of the masks. This catalog includes the information about the object in each slit as well as the measurement of the redshift. The 2. iraf.w05.m*.*.*.fits. These are 1-D extracted files in an iraf compatible format. The names of the files correspond to the mask, slit, and original id in the catalog used for selection. Unfortunately, due to an bug in the original extraction software, the primary target appears usually appears in the file named serendip1 and not the file with the object id.本压缩包包含MS 0451-03星系团天区中星系的已提取光谱观测数据。这批观测由凯克天文台（Keck Observatory）的DEIMOS设备获取。观测细节详见Crawford等人2011年发表于《天体物理学杂志》（ApJ）第741卷第98页的研究，DOI：10.1088/0004-637X/741/2/98。该论文附带的目录亦包含此类天体的补充信息。本次发布包含以下文件：1. w05.m*-crawford.fits：对应每个观测掩模的目录文件，该目录包含了每个狭缝中天体的相关信息以及红移测量结果。2. iraf.w05.m*.*.*.fits：采用IRAF兼容格式存储的一维提取光谱文件，文件名中的字段分别对应观测掩模、狭缝编号以及筛选时所用目录中的原始ID。遗憾的是，由于原始提取软件存在缺陷，目标天体通常会出现在名为serendip1的文件中，而非以天体ID命名的文件内。
