Results from the Bovy et al. (2012) mono-abundance papers

This module provides access to the fit results from Bovy et al. (2012a), Bovy, Rix, & Hogg (2012), and Bovy et al. (2012b). They can either be used through a python interface or are directly accessible through a FITS file (see below).

Jo Bovy - bovy at ias dot edu

Standard python setup.py build/install

Either

sudo python setup.py install

or

python setup.py install --prefix=/some/directory/

A Python interface to the results is available as:

import monoAbundanceMW as map
map.hz(-0.5,0.25)
443.2816423047887 #pc

for example. See the __init__.py file in monoAbundanceMW/ for more info on various functions.

The results are also available in this FITS file, which you can download by clicking on raw. This file has the fit results for each bin, and contains the [Fe/H], [a/Fe] that the bin is centered on, and all of the parameters describing the density and velocity dispersion. The parameter names are pretty self-explanatory, but here's a quick overview:

feh: metallicity
afe: alpha-enhancement
hz: scale height in pc
hr: scale length in kpc
hz_err, hr_err: errors on the two above
mass: total surface density in Msolar/pc^2 (note that there is a factor of (0.58-0.45)/(0.55-0.48) missing from the surface densities that they need to be multiplied with)
zmedian: median height of the data sample in pc (this is the pivot for
the kinematics fits)
sz: vertical dispersion in km/s at zmedian
p1: slope of the vertical dispersion in km/s/kpc
p2: second derivative of the vertical dispersion in km/s/kpc/kpc
hsz: radial scale length of the vertical velocity dispersion in kpc
sz_err, p1_err, p2_err, hsz_err: errors on the previous four
szp1_corr, szp2_corr, ...: correlation coefficients for the four
kinematics parameters
sr: radial dispersion in km/s at zmedian
hsr: radial scale length of the radial velocity dispersion in kpc
sr_err: error on sr

[For the radial velocity dispersion only the results from a fit with constant dispersion(height) are included, so the p1 and p2 parameters for sr are set to zero].
