26 5 月 This new slit size, estimated throughout the heavens, try 4 arcmin

Latter W

Regarding bluish sleeve an RCA CCD which have 1024 x 640 pixels of fifteen-micrometers-squared size along with the newest purple arm an effective GEC CCD which have 1152 x 770 pixels out of twenty two. The newest dispersion are 1. The initial a few twin spectra shelter the product range 3000-4720 angstroms regarding bluish sleeve and you may 6000-7250 angstroms at a negative balance sleeve. The remainder one or two twin spectra security the product range 3300-5160 angstroms regarding the bluish arm and you will 7130-8200 angstroms in debt sleeve. The brand new slit was established across the solar-antisolar direction, which in the course of the fresh observations was not far from perpendicular towards opinions, to reduce refraction effects. The fresh new comet occured at the center of the slit. At the end of this new observations the new level of one's comet try eleven amounts.

The fresh new spectrometers contained a few pairs from banking institutions out of filter systems, a couple of polarizations moments 128 channels regarding a hundred kHz resolution and 128 streams from 250 kHz quality in the step three mm

An effective spectroscopic simple star therefore the solar kind of stars sixteen Cyg An excellent and you will B were registered to allow pure calibration and subtraction of the soil continuum.
