Continuum (1.3 mm) and J = 2 − 1 ¹³CO, C¹⁸O, and C¹⁷O line emission towards GLMP 950. Top: Maps of the continuum (colour map) and ¹³CO J = 2 − 1 emission integrated over the whole line emission (contours) at 10%, 30%, 50%, and 70% of the peak value (6.2 Jy beam⁻¹ km s⁻¹). The continuum emission peaks at $\alpha ={19}^{\text{h}}{47}^{\text{m}}24\stackrel{\text{s}}{.}430$ and $\delta ={29}^{°}28\prime 13\stackrel{″}{.}556$. Bottom: Source-integrated spectra of the ¹³CO J = 2 − 1, C¹⁸O J = 2 − 1, and C¹⁷O J = 2 − 1 lines. The vertical line marks the inferred velocity of the source υ_LSR = 22 km s⁻¹.
