Figure 1

(a) The image of DDO 70, where red denotes infrared emission at 160 μm, green denotes the far-UV emission and blue denotes the atomic hydrogen 21 cm emission. (b) The image of DDO 53. (c) The image of DDO 50. All the white scale bars are 40″ across. (d) The CO J=2−1 spectra for region A in DDO 70. (e) The CO J=2−1 spectra for region A in DDO 53. (f) The CO J=2−1 spectra for region A in DDO 50. (g) The CO J=2−1 spectra for region B in DDO 50. The spectral channel width is 0.5, 1.0, 4.0 and 1.0 km s−1 for DDO70-A, DDO53-A, DDO50-A and DDO50-B, respectively, and the corresponding 1−σ continuum sensitivity is 3.94, 4.17, 3.13 and 4.89 mK, respectively.
