The Potsdam plates of the Carte du Ciel project: I. Present inventory and plate catalogue

We present an inventory ofthe Carte du Ciel CdC plates stored in the Astrophysical Institute Potsdam. The Potsdam CdC zone 32° to 39° was divided into 1232 areas and about 2200 plates from the first and second epochs were obtained within the framework of the CdC project. At present, only 977 plates 45 of all are stored in AIP, the others got lost during the Second World War. The plates for the first epoch measurements had been obtained during the period 1893 May– 1900 February. The plates for the second epoch 1913 August–1924 February can be separated into two time intervals according to the observer and the observing method used: from 1913 August till 1914 July, and from 1916 February to 1924 February. The present work aims to provide online access to the plate information, given in the plate catalogue and is the first step to online access to the plate images digitized with flatbed scanners.
