Sensor Modifiers

Source Galaxy Exploration Manual pg. 37
Various circumstances might modify the DC for the checks needed to ascertain information about a planet while using sensors in orbit. The following is a list of some of those circumstances and how they modify the DC. Modifiers from two or more different sources can stack (such as if a planet has both a thick atmosphere and an extreme magnetic field). Strange anomalies may hamper scanning at the GM’s discretion; see the Planetary Anomalies below.
