Introduction

This report summarizes deliberations of the MMA Frequencies Working Group, charged with reporting on the priorities for the frequency bands of the MMA receivers. This includes consideration of the positions of the rest wavelengths of important lines in the millimeter and submillimeter bands, as well as redshifted lines and continuum emission, especially dust.

In the first section, we discuss previous considerations of the siting of MMA frequency bands. In the second section, we consider the positions of the rest wavelengths of important lines relative to the atmospheric absorption in the millimeter and submillimeter bands, including redshifted lines and continuum emission, especially dust. For the centimeter window, the Sunyaev-Zeldovich effect drives the science, which is discussed in relation to placement of that band.
