# shapelimit



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



## s\_center\_x int float1 float2 float3


Range of 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 int float1 float2 float3


Range of 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\_sig\_x int float1 float2 float3


Range on the size of the major axis in arcsec



## s\_sig\_y int float1 float2 float3


Range on the size of the minor axis in arcsec



## s\_angle int float1 float2 float3

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



## s\_mag int float1 float2 float3


Range on the unlensed magnitude of the source



## index int float1 float2 float3


Range on the value of the Sersic index $n$ for sources modeled with Sersic profile.
