AtmosphereDensityProfile

class ctapipe.atmosphere.AtmosphereDensityProfile

Bases: abc.ABC

Base class for models of atmosphere density.

Methods Summary

__call__(height)	Returns
from_table(table)	return a subclass of AtmosphereDensityProfile from a serialized table
integral(height)	Integral of the profile along the height axis, i.e. the atmospheric depth \(X\).
line_of_sight_integral(distance[, …])	Line-of-sight integral from the shower distance to infinity, along the direction specified by the zenith angle.
peek()	Draw quick plot of profile

Methods Documentation

abstract __call__(height: astropy.units.quantity.Quantity) → astropy.units.quantity.Quantity

Returns

u.Quantity[“g cm-3”]

the density at height h

classmethod from_table(table: astropy.table.table.Table)

return a subclass of AtmosphereDensityProfile from a serialized table

abstract integral(height: astropy.units.quantity.Quantity) → astropy.units.quantity.Quantity

Integral of the profile along the height axis, i.e. the atmospheric depth \(X\).

\[X(h) = \int_{h}^{\infty} \rho(h') dh'\]

Returns

u.Quantity[“g/cm2”]:

Integral of the density from height h to infinity

line_of_sight_integral(distance: astropy.units.quantity.Quantity, zenith_angle=<Quantity 0. deg>, output_units=Unit("g / cm2"))

Line-of-sight integral from the shower distance to infinity, along the direction specified by the zenith angle. This is sometimes called the slant depth. The atmosphere here is assumed to be Cartesian, the curvature of the Earth is not taken into account.

\[X(h, \Psi) = \int_{h}^{\infty} \rho(h' \cos{\Psi}) dh'\]

Parameters

distance: u.Quantity[“length”]

line-of-site distance from observer to point

zenith_angle: u.Quantity[“angle”]

zenith angle of observation

output_units: u.Unit

unit to output (must be convertible to g/cm2)
