An Introduction to Coordinate System Conversions

In this section, we start to look at techniques for converting between different coordinate systems. At this stage, the tools we have available are Frames (§7), SkyFrames (§8), SpecFrames (§9), TimeFrames (§10) and various Mappings (§5). These are sufficient to allow us to begin examining the problem, but more sophisticated approaches will also emerge later (§14.2).
