The workshop has a “poster haiku” session, where one may summarize a poster in a single transparency and speak on it for a couple of minutes. I cannot count syllables, so I wrote a limerick instead:

For simple models, hardness ratios make for a useful grid;
But to describe hi-res coronal spectra they’re quite horrid.
So we went to find, with line ratios as witness,
Patterns and trends in a high-dimensional mess;
And extract stellar subclasses from the morass where it is hid.

Update: The poster is at CHASC.
