__call__(radius)

Call evaluate method of derived classes.

integral(rmin, rmax, separation, ndecade, squared=True)

Integrate dark matter profile numerically.

\[\begin{split}F(r_{min}, r_{max}) = \int_{r_{min}}^{r_{max}}\rho(r)^\gamma dr \\ \gamma = 2 \text{for annihilation} \\ \gamma = 1 \text{for decay}\end{split}\]

Parameters:

rmin, rmaxQuantity

Lower and upper bound of integration range.

separationndarray

Separation angle in radians.

ndecadeint, optional

Number of grid points per decade used for the integration. Default is 10000.

squaredbool, optional

Square the profile before integration. Default is True.

integrate_spectrum_separation(func, xmin, xmax, separation, ndecade, squared=True)

ndecadeint

Number of grid points per decade used for the integration.

squaredbool

Square the profile before integration. Default is True.

scale_to_local_density()

Scale to local density.
