Magnetic field segments derived from JCMT/POL2 850 micrion polarization observations toward the Central Molecular Zone

Catalogs of magnetic field segments derived from JCMT/POL2 850 micrion polarization observations toward the Central Molecular Zone (Lu et al. 2023, ApJ accepted, https://ui.adsabs.harvard.edu/abs/2023arXiv231201776L/abstract). The position angles are those of the magnetic field (i.e., polarization position angles rotated by 90 degree). The files 'CLOUDNAME_cloud_tran.mrt' are field segments within the boundaries of the clouds (see Figure 2 in the reference paper). Here 'CLOUDNAME' is one of the eleven clouds defined in the paper, including: 50kms, brick, CO002, DRb, DRc, DRd, DRef, fsc, sgrc, stone, and strawsticks. The files 'REGIONNAME_bin2_pdp3_deg.mrt' are field segments in the three large tiles, regardless of whether the segments are within a cloud or not (see the dashed magenta boxes in Figure 1 in the reference paper). Here 'REGIONNAME' is one of the three large tiles, i.e., dustridge, gc, and sgrcaround. Please check the Byte-by-byte Description inside the files for the meanings of the columns in the tables. Many thanks to August Muench for converting the files to machine readable tables.本数据集为针对银心分子区（Central Molecular Zone）的JCMT/POL2 850微米偏振观测数据所构建的磁场分段目录（Lu等，2023年，《天体物理学杂志》（Astrophysical Journal，ApJ）已接收，链接：https://ui.adsabs.harvard.edu/abs/2023arXiv231201776L/abstract）。其中的位置角为磁场的位置角，即对偏振位置角旋转90°后得到的数值。文件CLOUDNAME_cloud_tran.mrt存储了各云团边界范围内的磁场分段（详见参考文献中图2）。此处CLOUDNAME为文中定义的11个云团之一，具体包括：50kms、brick、CO002、DRb、DRc、DRd、DRef、fsc、sgrc、stone及strawsticks。文件REGIONNAME_bin2_pdp3_deg.mrt存储了三个大型观测天区块内的所有磁场分段，无论分段是否处于云团边界之内（详见参考文献中图1的品红色虚线框）。此处REGIONNAME为三个大型观测天区块之一，即dustridge、gc、sgrcaround。数据表各列的含义请查阅文件内附的逐字节数据说明（Byte-by-byte Description）。特别感谢August Muench将原始文件转换为机器可读数据表。
