Transient phase space showing the radio luminosity versus the variability timescale of several transient events observable in the radio sky. Overlaid are Effelsberg’s sensitivity curves for the Galactic distances of 0.1, 1, and 10 kpc as well as the cosmological distance of 1 Gpc and pulse widths from 0.109 to 13.98 ms (the used search width range of the SP search). The positions of the re-detected pulsars and RRAT are indicated with the black and grey ⊙ symbols, respectively.
