Spectrum will cycle through this grid NMOD times, omitting NSKIP-1 models from the . ... However, the input data following MODE must be repeated NMOD times in order to obtain equivalent results for each model in the grid. ...

... The accuracy to which you can trust the absolute flux calibration of your STIS spectroscopic data at slit center is limited by several factors including: . The accuracy of the absolute sensitivity calibration of the grating and central wavelength setting. ... The STIS spectrum of this star is then extracted over a standard aperture extraction box and the sensitivity required to return the known flux from the star is determined as a function of wavelength. ...

... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...

Optical Spectroscopy of the Eastern Filament of W50 O. Maryeva, P. Abolmasov, A. Burenkov and A. Moiseev Abstract: We present the results of long-slit and FPI spectroscopy of the Eastern optical filament of the radionebula W50, associated with the well-known peculiar binary SS433. ... Our results are consistent w ith the optical filaments being powered by the EUV/X-ray radiation from high-velocity shock waves in the Eastern lobe of W50 or from SS433. ...

False-color image of the dark cloud Barnard 68, prepared using data from the Herschel Space Telescope at different far-infrared wavelengths. ... This could be a cloud fragment in collision with Barnard 68. The wavelengths for the images are 100, 160, 250, and 350 micrometers, respectively. The image colors show the intensity of the radiation received at that wavelength, from purple and blue at low intensity to high intensities in red and white. ...
