两个Bok球状体L1253（CB 246）和CB 34分别在C_2S（21-10）跃迁和NH_3（1，1）和NH_3（2，2）反转跃迁中被映射。通过比较L1253（CB 246）的C2 S图谱与来自Lemme等人的相同小球的NH3图谱，由于物体的化学和动力学演化而产生成团的洋葱结构。从导出的参数来看，L1253（CB 246）和CB 34都接近维里平衡。
Two Bok globules, L1253 (CB246) and CB34, have been mapped in the C2S (21–10) transition and in the NH3 (1, 1) and NH3 (2, 2) inversion transitions, respectively. By comparing the C2S map of L1253 (CB246) with the NH3 map of the same globule from Lemme et al., a clumped onion structure results as a consequence of the chemical and dynamical evolution of the object. From the derived parameters it appears that both L1253 (CB246) and CB34 are close to virial equilibrium.
