Regarding bluish sleeve an enthusiastic RCA CCD that have 1024 x 640 pixels out of 15-micrometers-squared proportions and in the new red case good GEC CCD having 1152 x 770 pixels off twenty-two. The fresh new dispersion is actually step one. The original several dual spectra shelter the product range 3000-4720 angstroms on the bluish case and you can 6000-7250 angstroms at a negative balance sleeve. The rest a couple twin spectra defense the product range 3300-5160 angstroms throughout the bluish sleeve and you may 7130-8200 angstroms at a negative balance arm. The brand new slit is actually dependent over the solar-antisolar assistance, which in the course of new observations wasn’t away from perpendicular on panorama, to attenuate refraction effects. The fresh new comet occured in the centre of your slit. At the end of the new findings the brand new level of the comet is actually eleven level.

An effective spectroscopic simple celebrity and also the solar power variety of stars 16 Cyg An excellent and you may B was submitted to let sheer calibration and you can subtraction of your own dust continuum. Regrettably, the observing criteria were mostly nonphotometric. The newest spectra let you know with high code/noise the new basic pollutants from OH, NH, CN, C3, CH, C2, [OI], and you can NH2. Brand new ion pollutants are a lot fainter. CO2^+, OH^+, CO^+, N2^+, and you will Liquids^+ can be found. The spectra are being processed to recuperate and compare this new pollutants of one’s bluish and you will red escort sites Mesquite TX CN bands, away from OH and [OI], off NH and you will NH2, as well as all ions.
