Description: 3D data cube of 13CO emission in Perseus. Data were obtained at FCRAO using the On-the-Fly (OTF) mapping method during 2002-2004. Units are uncorrected antenna temperature (TA*) in Kelvin. Up-to-date values of the forward-scattering efficiency (eta_n) can be obtained from the FCRAO website. Velocities are in m/s. The map has a Samsom-Flamsteed (SFL) projection. Contact Person: Naomi Ridge, Harvard-Smithsonian Center for Astrophysics Telescope: FCRAO Status: Finished, although some observations to improve the noise are ongoing. Sampling: The data were taken in OTF mode, which means they are over-sampled at irregular intervals. The spectra are re-gridded to 23" pixels (approximately Nyquist sampled). Areal Coverage: Approx 6.25 by 3 degrees Map Center (Galactic): l = +159:13:00 b = -19:15:00 Map Center (J2000): RA = 03:37:00 Dec = +31:49:00 Comments on Resolution: The resolution of FCRAO at 110GHz is approximately 46". Data are convolved onto a 23" grid. Publications: None yet
