jeanspy.model.ProjectedExponentialModel.mean_density_2d

Class and construction: ProjectedExponentialModel.

ProjectedExponentialModel.mean_density_2d(R_pc)[source]#

Average surface density inside a circular aperture.

Notes

Inputs and units. Positive projected radius R_pc in pc, scalar or NumPy array.

Returns and shape. cdf_R(R)/(pi*R**2), in pc^-2 with radius shape.

Validity. Use R>0; the elementary ratio is not a numerically regularized central limit.
