Map of the Taurus molecular cloud obtained by the James Clerk Maxwell Telescope using the ¹²CO (J = 3−2) emission (integrated between 2.0 and 11.0 km s⁻¹). Areas also mapped with ¹³CO (J = 3−2) emission (integrated between 4.9 and 9.1 km s⁻¹) are indicated by rectangular boxes. We calculated the optical depth property in the subregion L1495 E, whereas CIDA 1 is located in the region L1495 W. The image is adapted from right-hand panel of Fig. 1 in Davis et al. (2010).
