Detailed Description

Generate and return the conversion of an input natural logarithm of peak photon flux in 64ms timescale to an effective triggering peak photon flux both in the BATSE detection energy range \([50, 300]\kev\).

See the Eqn A4 of Shahmoradi and Nemiroff 2015, MNRAS, Short versus long gamma-ray bursts for more details.
The observed T90 duration of the event is necessary as input to account for varying duration of short GRBs and their effects on the triggering mechanism.

Parameters

[in]	logPPF64	: The input scalar, or array of the same rank as other input array-valued arguments, of type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128), containing the natural logarithm of the 64ms Peak Photon Flux of an event in units of \([\ms{photons} / \ms{sec}]\).
[in]	logT90	: The input scalar, or array of the same rank as other input array-valued arguments, of the same type and kind as logPPF64, containing the natural logarithm of the T90 duration-definition measure of a GRB in units of seconds.

Returns

logEffPPF : The output scalar or array of the same rank as the input arguments of same type and kind as the input arguments, containing the natural logarithm of the effective 1024ms triggering peak photon flux in the BATSE nominal detection energy range, such that the effects of multiple triggering timescale of BATSE detectors are compensated for, as if all BATSE GRBs with different observed durations were detected by the same duration-agnostic gamma-ray detector and triggering mechanism.

Possible calling interfaces ⛓

use pm_batse, only: getLogEffPPF
 
logEffPPF = getLogEffPPF(logPPF64, logT90)

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.

Note

The following relationship holds: logPPF64 - getCorrectionLogEffPPF(logT90) = logPPF1024 - THRESH_ERFC_BASE.
