Notes. Comparison of IR and (0, 11c, 0) maser luminosities. Columns are (left to right) the name, flux density in the 12 μm IRAS band (taken from the IRAS Point Source Catalog https://heasarc.gsfc.nasa.gov/W3Browse/all/iraspsc.html), and the photon rates emitted in the maser line and at 12 μm in a wavelength range that corresponds to the velocity range covered by maser emission (taken from Table 3). In the two cases for which no maser line was detected (X Cnc and U Hya), upper limitswere calculated using the velocity range covered by emission in the (0,0,0) line and the 3σ upper limitsfor the maser-line integrated flux density given in that table.
