Although words are same, the first impression and their usage is quite different from society to society (even among statisticians). One word I’m very reluctant to use both to astronomers and statisticians is model. I’m quite confused at the reactions from both sides. To clarify meanings, implications, or intentions, some clever adjectives must accompany these common words; however, once one gets used to these jargons, adjectives are felt redundant to your fellow scientists/colleagues, whereas the other gets lost and seeks explanation of the usage by related examples and backgrounds.

Not only simple words, like model and density, there are more jargons requires inter-disciplinary semantic experts. Yet, patience of explaining and open-mindedness would easily assist to get over language barriers in any interdisciplinary works.

First, there is the physical model, which could mean either our understanding of what processes operate on a source (the physics part, usually involving PDEs), or the mathematical function that describes the emission as a function of observables like location, time, or energy (the astronomy part, usually the shape of the spectrum, or the time evolution in a light curve, etc.)

The data model on the other hand describes the organization of the observation. It is this which tells us that there is a fundamental difference between an effective area and a response matrix, and conversely, that the point spread function and the line response function are the same beast. This kind of thing, which I suppose is a computer science oriented view of the contents of a file, is crucial for implementing and running something like the Virtual Observatory.

This is not a high energy lecture note; therefore, statisticians interested in high energy are encouraged to visit Astro Jargon for Statisticians and CHASC.
