The brand new reflectance spectra was basically gotten by using the 2
Zero mineralogical data is found in forming the latest groups, although exact same spectral suggestions which is used inside the classifying asteroids contained in this wavelength part will give a harsh translation out of skin structure
New EFOSC2 spectrograph is armed with a beneficial three hundred ll/mm grating coating a good spectral variety 3500-9000 angstroms; new B&C spectrograph that have a great 150 ll/mm grating coating an excellent spectral assortment 3700-7800 angstroms. Prejudice, flat-career, calibration lamp, important stars and you may solar analogs was indeed protected to help you wavelength and you can flux calibrate the fresh new asteroidal spectra in order to get rid of the solar power contribution. The fresh new prevention remains ongoing and also at present analysis out-of the fresh Esto 2. The primary purpose of the research of them spectra is to look at the the outside composition of the asteroid as a way to find out about their origin and creation and, a great deal more generally, of AAA asteroids in addition to their you’ll loved ones with cometary nuclei. This new shape, and that looks here in the tough content, means that the main purpose of the study of those spectra will be to have a look at the exterior structure of the asteroid into the a keen efforts to learn about its resource and you can development and, a great deal more basically, of your AAA asteroids in addition to their possible family relations which have cometary nuclei.
