Estimated maximum VHE γ-ray luminosities of the target microquasars, which would still be consistent with a non-detection given the flux upper limits presented in Table 4.
|Target||Maximum distance estimate||Ethresh||Luminosity above Ethresh|
|GRS 1915+105||10.6||562||<2.3 × 1034|
|Cir X-1||10.2||562||<3.4 × 1034|
|V4641 Sgr||6.9||237||<2.5 × 1034|
Notes. Source distances correspond to the largest estimate that was found in the literature (see Sect. 2). The energy threshold of Cherenkov telescope arrays increases with observational zenith angle.
