The γ-ray light curves in the TeV energies (>100 GeV) expected from considered MSP binary systems: PSR J1023+0038 (on the left), PSR J1810+1744 (left middle), PSR J1816+4510 (right middle), and PSR B1957+20 (right). Specific curves show the results for different inclination angles of the binary systems: i = 0° (dotted), 30° (dot-dot-dashed), 45° (dashed), 60° (solid), and 90° (dot-dashed). The phase is counted from the location of the MSP in front of the companion star. The parameters of the companion stars and the binary systems are reported in Table 1. It is assumed that the MSP moves in a circular orbit around the companion star. The parameters describing the spectrum and escape of electrons are the same as in Fig. 3. The injection place of electrons is assumed to be at the apex of the collision region (described by Rsh in Table 1). The γ-ray fluxes are collected in the range of phases with the width equal to 0.05.
