FCRAO CO Survey of M31

The FCRAO CO Survey of M31 covers the entire southern half of that galaxy. It is regularly sampled on the rectangular (X,Y) coordinate system first introduced by Baade & Arp (1964). X runs along the major axis from South to North, and Y along the minor axis from West to East.The velocities are relative to the LSR
The sensitivity is quite homogeneous around 45-50 mK (T_MB) per 3.25 km s^-1 spectral resolution element across the entire map. The size of the cube is (146x75x36) in (V, X, Y), and the steps are 3.25 km s^-1 in velocity and 50 arcseconds in X and Y.
The cube is in FITS format. If you try to use the data, and have any problem, please don't hesitate to contact me at l.loinard@astrosmo.unam.mx.
