pint.templates.lcprimitives.LCTopHat

class pint.templates.lcprimitives.LCTopHat(**kwargs)[source]

Bases: LCPrimitive

Represent a top hat function.

Parameters:

Width right edge minus left edge Location center of top hat

Generally, class-specific setup work is performed in init. Here, init is called and certain guaranteed default members are established.

eval_string()

Return a string that can be evaluated to instantiate a nearly- identical object.

fwhm()

Return the full-width at half-maximum of the light curve model.

get_bounds([free])

get_errors([free])

get_free_mask()

Return a mask with True if parameters are free, else False.

gradient(phases[, log10_ens, free])

Return the gradient of the primitives wrt the parameters.

gradient_derivative(phases[, log10_ens, free])

Return d/dphi(gradient).

hwhm([right])

Return the half-width at half-maximum of the light curve model.

init()

integrate([x1, x2, log10_ens])

Base implemention with scipy quad.

is_energy_dependent()

is_two_sided()

True if primitive is asymmetric.

num_parameters([free])

parse_kwargs(kwargs)

random(n)

Default is accept/reject.

sanity_checks([eps])

A few checks on normalization, integration, etc.

set_errors(errs)

set_location(loc)

set_parameters(p[, free])

hwhm(right=False)[source]

Return the half-width at half-maximum of the light curve model.

__call__(phases, wrap=True)[source]

Call self as a function.

random(n)[source]

Default is accept/reject.

center_gauss_prior(enable=False)

[Convenience] Set gauss mode to current params.

closest_to_peak(phases)

Return the minimum distance between a member of the array of phases and the position of the mode of the primitive.

derivative(phases, log10_ens=3, order=1)

Return d^np(phi)/dphi^n, with n=order.

dict_string()

Return a string to express the object as a dictionary that can be easily instantiated using its keys.

enable_gauss_prior(enable=True)

[Convenience] Turn on gaussian prior.

eval_string()

Return a string that can be evaluated to instantiate a nearly- identical object.

fwhm()

Return the full-width at half-maximum of the light curve model.

get_free_mask()

Return a mask with True if parameters are free, else False.

get_width(error=False, hwhm=False, right=False)

Return the width of the distribution.

Parameters:
  • error (bool) – if True, return tuple with value and error

  • hwhm (bool) – if True, scale width to be HWHM

  • right (bool) – if True, return “right” component, else “left”. There is no distinction for symmetric dists.

gradient(phases, log10_ens=3, free=False)

Return the gradient of the primitives wrt the parameters.

gradient_derivative(phases, log10_ens=3, free=False)

Return d/dphi(gradient). This is needed for computing the hessian of the profile for parameters that affect the timing model and hence pulse phase.

integrate(x1=0, x2=1, log10_ens=3)

Base implemention with scipy quad.

is_two_sided()

True if primitive is asymmetric. Default is False, two-sided child classes should override.

sanity_checks(eps=1e-06)

A few checks on normalization, integration, etc.
