shapemodel

Under this identifier are defined the parameters that define a source shape.

s_center_x float

Position along the X axis for the center of the source in arcsec. The reference point for this range is the barycenter of sources is attached to a system of multiple images, or the reference point defined in the .par file if not.

s_center_y float

Position along the Y axis for the center of the source in arcsec. The reference point for this range is the barycenter of sources is attached to a system of multiple images, or the reference point defined in the .par file if not.

s_sigx float

Value of the size of the major axis in arcsec

s_sigy float

Value of the size of the minor axis in arcsec

s_angle float

Value of the orientation of the ellipse defining the source. The angle is defined anti-clockwise from west to north axis.

s_mag float

Value of theunlensed magnitude of the source

index float

Value of the Sersic index n for sources modeled with Sersic profile.

z float

Redshift of the source.

id string

Identifier of the source.

type int

Surface brightness density type

1: Velocity field I(r)=sign(y) I_0 \sqrt{|y|}
2: Exponential disk I(r)=I_0 \exp(-r)
3: 2D Gaussian I(r)=I_g \exp(-0.5\,r^2)
4: Sersic I(r)=I_0 \exp(-r^{1/n})
5: Uniform disk within radius I(r)=I_0 for r<a\ b

with I_0=10^{-0.4\,({\rm s_{mag}}-26)} and I_g = 10^{-0.4\,({\rm s_{mag}}+48.57)+29}
