Fast radio bursts: search sensitivities and completeness

In this paper we identify some sub-optimal performance in algorithms that search for Fast Radio Bursts (FRBs), which can reduce the cosmological volume probed by over 20%, and result in missed discoveries and incorrect flux density and sky rate determinations. Re-calculating parameters for all of the FRBs discovered with the Parkes telescope (i.e. all of the reported FRBs bar one), we find some inconsistencies with previously determined values, e.g. FRB 010125 was approximately twice as bright as previously reported. We describe some incompleteness factors not previously considered which are important in determining accurate population statistics, e.g. accounting for fluence incompleteness the Thornton et al. all-sky rate can be re-phrased as ~2500 FRBs per sky per day above a 1.4-GHz fluence of ~2 Jy ms. Finally we make data for the FRBs easily available, along with software to analyse these.

Five new fast radio bursts from the HTRU high-latitude survey at Parkes: First evidence for two-component bursts (2015, methodology): “Using GPU technology, this pipeline is considerably quicker than the previous processing while allowing a larger range of parameters to be searched (Keane & Petroff 2015).”
Fast radio burst source properties and curvature radiation model (2017, background): “They have an all-sky rate of ∼ 103 to 104 day−1 above fluence ∼ 1 Jy ms (Thornton et al. 2013; Keane & Petroff 2015; Rane et al. 2016; Champion et al. 2016).”
A burst in a wind bubble and the impact on baryonic ejecta: high-energy gamma-ray flashes and afterglows from fast radio bursts and pulsar-driven supernova remnants (2016, background): “Interestingly, despite being relatively common (∼ 10 % of core-collapse supernovae; Thornton et al. 2013; Keane & Petroff 2015; Law et al. 2015), the origin of FRBs is still unknown.”
MERGERS OF CHARGED BLACK HOLES: GRAVITATIONAL-WAVE EVENTS, SHORT GAMMA-RAY BURSTS, AND FAST RADIO BURSTS (2016, background): “…event rate density may be estimated as ρ̇FRB= 365ṄFRB (4π/3)D3z ≃ (5.7× 103 Gpc−3 yr−1) × ( Dz 3.4 Gpc )−3 ( ṄFRB 2500 ) , (26) where ṄFRB is the daily all-sky FRB rate which is normalized to 2500 (Keane & Petroff 2015), and Dz is the comoving distance of the FRB normalized to 3.4 Gpc (z = 1).”
A NEW ELECTRON-DENSITY MODEL FOR ESTIMATION OF PULSAR AND FRB DISTANCES (2016, background): “One FRB has been found to emit repeated pulses (Spitler et al. 2016), suggesting a relationship with pulsars, especially RRATS (see Keane & Petroff 2015), but their origin remains a topic of great debate.”
The Detection of an Extremely Bright Fast Radio Burst in a Phased Array Feed Survey (2017, background): “…Wayth et al. 2011; Caleb et al. 2016; Spitler et al. 2016; Masui et al. 2015; Chatterjee et al. 2017) and an estimated rate of ∼ 3000 events sky−1 day−1 above a fluence of 2 Jy ms (Keane & Petroff 2015; Champion et al. 2016), fewer than thirty such bursts are still known1 (Petroff et al. 2016).”
FRBCAT: The Fast Radio Burst Catalogue (2016, methodology): “Finally, a standard pulse search algorithm was used, which consists in convolving the time series with a set of top-hat pulse templates (Lorimer & Kramer 2004), here with widths covering all values from 1 1https://github.com/evanocathain/destroy gutted 2http://psrchive.sourceforge.net/ 3https://gith”
CMB-S4 Science Case, Reference Design, and Project Plan (2019, unknown): “[470, 471, 472]), with around 20 detected to date.”
The SUrvey for Pulsars and Extragalactic Radio Bursts – II. New FRB discoveries and their follow-up. (2017, unknown): “Following Keane & Petroff (2015) and considering those FRBs in the fluence complete region, we estimate a rate above ∼2 Jy ms of 1.7+1.5−0.9 × 103 FRBs/(4π sr)/day.”
