No mineralogical info is utilized in developing brand new classes, nevertheless the same spectral pointers which is used from inside the classifying asteroids inside wavelength part gives a rough interpretation off epidermis constitution

The latest EFOSC2 spectrograph is equipped with a great three hundred ll/mm grating level a great spectral range 3500-9000 angstroms; this new B&C spectrograph with a good 150 ll/mm grating level a spectral diversity 3700-7800 angstroms. Bias, flat-community, calibration light, fundamental superstars and solar analogs have been secure so you’re able to wavelength and you may flux calibrate brand new asteroidal spectra in order to get rid of the solar power contribution. New protection continues to be beginning and at present studies away from the fresh Eso 2. The principal function of the research of those spectra is always to browse the the exterior structure of your asteroid in an effort to find out about its provider and you will creation and, significantly more essentially, of your AAA asteroids in addition to their you’ll loved ones which have cometary nuclei.
