The Role of Magnetic Fields in Triggered Star Formation of RCW 120

The JHK-band starlight polarization of background stars behind the Galactic HII region RCW 120. Each ascii file contains the starlight polarization in one passpand (J, H, K).本数据集为银河系电离氢区（HII region）RCW 120后方背景恒星的JHK波段星光偏振数据。每个ASCII文件包含一个波段（J、H、K）对应的星光偏振信息。
