Here is the outline of the current algorithm to choose the (possibly the most reasonable) Prime source when primestyle =auto. ... the proposed source, if the proposal source is within the FOV (of RGS) and is not confused with other EPIC sources. A likely scenario is this: the central chip of EPIC is used in the timing mode, where no EPIC source list is extracted; as a result no source appears at the proposed position, which is most likely to be at the EPIC central chip. ...

We have reviewed the characteristics of the extended red emission (ERE) as observed in many dusty astronomical environments, in particular, the diffuse interstellar medium of the Galaxy. ... We have compared the photoluminescence properties of a variety of carbon- and silicon-based materials proposed as sources for the ERE with the observationally established constraints. We found that silicon nanoparticles provide the best match to the spectrum and to the efficiency requirement of the ERE. ...
