1.Search spectra in database:

The logical AND operation is performed between the three criteria (empty means "all"). First 50 entries are shown. As criteria can be any of the following: asteroid number (ex: 1, 5143), asteroid designation (ex: 1989YK8), UAIcode of the telescope (ex: 586), observation date (ex: 2003-03-31), the article where the spectrum was published (ex:


2.Download file from database:

Insert file name, which can result from a search in database or by uploading/obtaining a temporary file (ex: Heracles_20020829_950_00, tempspec1719, tempspec_MySpec).


3.Upload temporary spectrum in database

Your file should contain at least 2 columns: wavelengt and reflectance. First column is interpreted as wavelength and the second one as reflectance. Size is limited to 10Mb.

Please be patient while gathering and sorting information

4. Concatenate spectra

Insert the file names for the two spectra (ex: Spectrum A:Heracles_19911214_697_00, Spectrum B:Heracles_20020829_950_00).


5. Clear temporary file

Insert your temporary filename (ex: tempspec1719, tempspec_MySpec).
