The james clerk maxwell telescope nearby galaxies legacy survey - ix. 12co j = 3→2 observations of ngc 2976 and ngc 3351

We present 12 CO J=3!2 maps of NGC 2976 and NGC 3351 obtained with the James Clerk Maxwell Telescope (JCMT), both early targets of the JCMT Nearby Galaxy Legacy Survey (NGLS). We combine the present observations with 12 CO J=1!0 data and nd that the computed 12 CO J=3!2 to 12 CO J=1!0 line
