    If you have them expressed as positive numbers with North/South and East/West letters then simply switch the latitude from S to N (or from N to S), switch the longitude from E to W (or W to E) and replace the number with 180 minus the number. Hence (10.-104) becomes (-10,76) and 40S 19W becomes 40N (180-19)E or 40N 161E.

Since the Earth's atmosphere absorbs the vast majority of X-rays , they are not detectable from Earth-based telescopes ; therefore space-based telescopes are required to make these observations.
