... Nebulae are clouds of gas and dust in space. ... These clouds come in many different varieties: some are the remains of dead stars, while others are areas of vigorous star birth, like this one. In fact, two different types can be seen in this striking new image: emission nebulae and reflection nebulae. ... The bluish patch next to the red emission nebula shows light from recently formed stars being scattered in other words, reflected in many different directions by these tiny particles. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...
