We examine colors from 3.6 to 24 ЮМm as a function of metallicity (O/H) for a sample of 34 galaxies. ... They display an abrupt shift in the 8 ЮМm-to-24 ЮМm color for metallicities between one-third and one-fifth of the solar value. ... This result is most simply interpreted as being due to a weakening at low metallicity of the mid-IR emission bands usually attributed to PAHs (polycyclic aromatic hydrocarbons) relative to the small-grain dust emission. ...

... There are number of features that can be set by the user in the Sparkle Dialog box. ...

The threshold value is currently a slider/text field pair which have a precision of .0001. ... Like the Threshold value, the Flare Intensity has both a slider and a text input field for specifying its value. ...

To change the Scaling Function (how pixel values are binned into color levels): . ... For example, the basic grey-scale color map specifies no intensity for any color at the lowest color level, full intensity for all colors at the highest color level, with the red, green and blue intensities varying linearly for intermediate levels. ... At low bias, low color levels (i.e., low pixel values) will have non-zero intensities, while at high bias only high pixel values will have non-zero intensity. ...

Colors are given essentially in the UBV system. They are : . total asymptotic colors ubt for (U-B)T . total asymptotic colors bvt for (B-V)T . effective colors ube for ((U-B)e (colors within the effective aperture in which half the total B-flux is emitted) . effective colors bve for ((B-V)e (same as for ube) Total assymptotic colors bvtc and ubtc are corrected for galactic extinction, inclination and redshift effect (see e.g. btc documentation) .

This is a color composite image made by Karen Gloria at Hopkins Observatory using a 6-inch refractor and a 512x512 element CCD detector. This is the famous Trifid Nebula, often photographed. It is a nice illustration of the combined effections of ionization and scattering caused by the large yield of blue and UV photons from newly formed massive stars.
