Hi,
I'm a bit fuzzy on these concepts. If I have a DPT station of strength 750, it is 750 against thermal or grav, or both? And if I have an enemy ship using its active sensor, generating a GPS of 4500, it means that I'll detect it at a distance of 4500 x 750 x whatever_coefficient_shouldd_apply, right (i.e range is purely proportional to both signature and sensor strength)
also, is
Active sensor emission = EM emission = GPS ?
