The silicates that produce the 10 and 18 micron features appear to be broadly similar to terrestrial minerals such as Forsterite and Enstatite. ... Where pre-solar silicate dust grains can be isolated from meteorite material, these also tend to be Mg-rich silicates rather than Fe-rich silicates. ... It has been suggested that the interstellar silicate grains have a different 10 micron feature profile than what is observed for the silicates around evolved stars. ...

... User Guide ] Task: clean Purpose: Apply Hogbom, Clark or Steer CLEAN algorithm to a map Categories: deconvolution CLEAN is a MIRIAD task that performs a hybrid Hogbom/Clark/Steer Clean algorithm, which takes a dirty map and beam, and produces an output map which consists of the Clean components. This output can be input to SELFCAL to self-calibrate visibilities, or input to RESTOR to produce a "clean" image. ... Key: map The input dirty map, which should have units of Jy/beam. No default. ...

Electron-Bombarded, Back-Illuminated CCD Sensors . For Low-Light-Level Imaging Applications . ... Damage to the gate structure oxide layers from keV level X-rays will likely result in increased dark current and decreased full-well capacity. ... Figure 14 shows the increase in dark current versus incident electron energies. ... The back-thinned CCD's 'lifetime' is defined, herein, to be a 50 electron per pixel increase in CCD dark current per 16.7 millisecond integration period. ...

The laboratory has developed a fabrication technology of boron/aluminium structural elements that does not involve high-temperature/high-pressure equipment which is usualle very expensive. ... For example, to produce boron/aluminum tubes with longitudinal reinforcement, see Fig.1 for examples, which are characterized in Table 1, we have constructed a simple equipment (Fig.2) based on a commercially available furnace. ...

... badpixfind searches for pixels identified as containing no useful data, and uses this information to produce an output file. ... A bad pixel map (or mask) can also be produced. An important point regarding the bad pixels is that there are essentially three separate (though not exclusive) sets of bad pixels that must be dealt with. ... The user is able to specify maximum and minimum allowed values (via the parameters lothresh and hithresh ) to screen for hot and dead pixels. ...
