Results of γ-ray flux intensity map at 50 TeV generated for different values of D₀. Panels (a)–(d) give the results for D₀ = 4.8 × 10²⁴ cm² s⁻¹, 1.2 × 10²⁵ cm² s⁻¹, 2.8 × 10²⁵ cm² s⁻¹, and 6.9 × 10²⁵ cm² s⁻¹, respectively. For comparing with the physical image shown in the LHAASO catalog, the coordinate system used here is the J2000 equatorial frame. The other parameters adopted in the calculation are d = 0.4 kpc and v = 1600 km s⁻¹. The white arrow indicates the proper motion direction of the pulsar, while the green star marks the current position of the pulsar.
