Abstract
There is a relevant and growing effort in Astronomy to store observations in Virtual Observatories to make better use and exploitation of modern and archival data. In that perspective, we are in the process of not only digitalizing the Tonantzintla Schmidt Telescope plate archival (about 15000 plates from 1942-1995), but actually developing a semi-automatic system to process the large amount of direct-imaging and objective-prism data into a homogenous and calibrated set, in order to create an astronomically useful catalogue for data mining and analysis. In particular, for the 4120 spectroscopic plates, the system consists of a series of algorithms that: locate and extract spectra; determine and apply the proper wavelength calibration; carry on the astrometry solution; correlate the astrometry with direct images of the archive (when available); and to label all identifiable objects. In this work we discuss the overall strategy to be implemented and present preliminary results.
