Finally, in Table \[global\] we also present the MIR luminosities of both the LW2 and LW3 filters for each galaxy of our sample. One can clearly see that despite the activity in these systems, the MIR spectrum contains only a small fraction ($<$5%) of their energy which is mostly emitted at longer wavelengths in the far-infrared (FIR). This is in sharp contrast from what is seen in normal late type galaxies where $\sim$15% of the luminosity is emitted between 5–20$\mu$m [@Dale2001]. In the same table we include the L$_{\rm
IR}$(L$_{\sun}$)/M$_{\rm H_2} $(M$_{\sun}$) ratio which traces the efficiency of molecular gas consumption, via either star formation or AGN activity, as well as the production of high energy photons which in-turn are reprocessed into infrared via dust absorption and/or scattering. As expected the reported values for our sample are typical of ultraluminous galaxies while ormal spiral galaxies such as the Milky Way have a ratio of 1–10L$_{\sun}$M$_{\sun}$$^{-1}$, while starbursts such
