Abstract:
We present a table of new "classical" model photospheres for M dwarfs
computed with an extensive set of atomic and molecular opacities
treated with the accurate and realistic opacity sampling technique.
The models of this grid are described and analysed in a companion
paper (Brett 1995, A&A, in press)
