Caption: Figure 1.
The X-ray luminosity versus redshift of 31 FXTs. The solid (black) curve shows the truncation boundaries assuming a limiting X-ray flux of Flimit = 4.5 × 10−11 erg cm−2 s−1 with a fixed photon index ΓWXT = 1.59. The associated set Mi is shown in the red rectangle, and Ni is shown in the blue rectangle.
