VLBI observations of the 6.7 and 12.2 GHz methanol masers associated with NGC 6334F
S. P. Ellingsen, R. P. Norris, P. J. Diamond +12
We present milliarcsecond resolution images of the 6.7 and 12.2 GHz methanol maser emission associated with the well-known star formation region NGC 6334F. The images agree well wi…
