In ICRAR/ProFit: Fit Projected 2D Profiles to Galaxy Images

Initial 2D Sersic Model Image Parameters

Description

Rough initial 2 component 2D Sersic model parameters for the provided model images.

Usage

data("ExampleInit")

Format

A data frame with 39 observations on the following 10 variables.

CATAID

GAMA CATAID reference

sersic.xcen1

x centres of the 2D Sersic profiles

sersic.ycen1

y centres of the 2D Sersic profiles

sersic.mag1

Total magnitudes of the 2D Sersic bulge profiles

sersic.mag2

Total magnitudes of the 2D Sersic disk profiles

sersic.re1

Effective radii of the 2D Sersic bulge profiles

sersic.re2

Effective radii of the 2D Sersic disk profiles

sersic.nser1

Sersic indices of the 2D Sersic bulge profiles

sersic.ang2

Orientation of the major axis of the disk profile in degrees

sersic.axrat2

Axial ratios of Sersic disk profiles defined as minor-axis/major-axis

Details

These rough initial guesses of the galaxy models were derived from single Sersic fits taken from Lange et al 2015.
