is split into spectral colours, corresponding to wavelength. Red light has long wavelengths, blue light has short wavelengths. from hot objects are continuous , like a rainbow . atoms only emit light of specific colours, revealing their fingerprints as a line spectrum . atoms in front of a hot object absorb light at these colours, giving an absorption spectrum . are predominantly absorption spectra . next

... HST . FUV-MAMA Repeller Off as an Available Mode for High Resolution Spectroscopy . ... Data . ... HST Overview . Overview . ... Retrieving HST Data . ... We find that the FUV-MAMA has improved resolving power (at the cost of sensitivity) when the repeller-wire high-voltage is turned off. ... To fully realize the increase in resolution provided by this mode, users will have to reprocess the data on their own using the CALSTIS package in STSDAS with parameters set for HiRes pixels. ...

On 19/20 October 1995 we used GRIM II to attempt spectroscopy of the 2.3 micron CO absorption band in stellar clusters. ... Read Noise Our typical backgrounds in 60s were about 100 DN (about 500 e), and so for faint objects our noise is utterly dominated by the read noise of about 110 e. We can think of three ways to improve this situation: integrate longer; reduce the read noise; or implement multiple reads. ... Flats The quartz lamps were too dim for flats. ...

We would like to announce the release of Version 3.0 of the CHIANTI database for astrophysical spectroscopy. This now extends the database to include the 1 - 50 wavelength region. The additions to the database are described in a paper `CHIANTI - an atomic database for emission lines, IV - Extension to X-ray Wavelengths' by K.P. Dere, E. Landi, G. Del Zanna, and P.R. Young and has been submitted to the Astrophysical Journal Supplement Series. ... http://wwwsolar.nrl.navy.mil/chianti.html . ...
