Context. The historic plates of the Carte du Ciel , an international cooperative project launched in 1887, offers valuable first-epoch material for determining of absolute proper motions. Aims. We present an original method of digitizing and astrometrically reducing Carte du Ciel plate material using an inexpensive flatbed scanner, to demonstrate that for this material there is an alternative to more specialized measuring machines that are very few in number and thus not readily available. The… 

Digitization and astrometric calibration of Carte du Ciel photographic plates with Gaia DR1

Context. Carte du Ciel was a global international project at the end of the nineteenth and beginning of the twentieth century to map the sky to about magnitude 14 on photographic plates. The full

Digitization, Measurement, and Analysis of a 1905 Barnard Atlas Photographic Plate

In the second paper in this series, we improve on our previous demonstration of the ability of a commercially available graphic arts scanner and cost-effective analysis tools to produce

Precise Photometric Measurements from a 1903 Photographic Plate Using a Commercial Scanner

We demonstrate the feasibility of determining magnitudes of stars on archival photographic plates using a commercially available scanner. We describe one photometric approach that could serve as a

Digitization and reduction of old astronomical plates of natural satellites

Old astrophotographic plates are precious sources of historical data for astronomical studies, especially regarding the improvement of natural satellite orbits. Today, with the advent of new,

Evaluating Commercial Scanners for Astronomical Image Digitization

. Many organizations have been interested in understanding if commercially available scanners are adequate for scientifically useful digitization. These scanners range in price from a few hundred to a

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

We present an inventory of the 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

VaST: A variability search toolkit

A modified commercial scanner as an image plate for table-top optical applications.

A reliable, accurate, and inexpensive optical detector for table-top applications based on a commercial high resolution office scanner coupled to a projection plate, allowing recording of sizeable images without systematic errors associated with coupling optics aberrations.

Comparative performance of selected variability detection techniques in photometric time series data

Photometric measurements are prone to systematic errors presenting a challenge to low-amplitude variability detection. In search for a general-purpose variability detection technique able to recover
