File size: 8.1 MBAstrometrica is a interactive software tool for scientific grade astrometric data reduction of CCD images, focusing on measurements of the minor bodies of the solar system (asteroids, comets and dwarf planets).

The current version for the Windows 32bit operating system family is the successor of a DOS based software that was used for astrometric data reduction of photographic films (1990), and later CCDs (1993).

Features of the current version include:Reads FITS (8, 16 and 32 bit integer files) and SBIG image files.

The size of the images is only limited by the available memory.

Automatic image calibration (Dark Frame and Flat Field correction).

Blinking with automatic image alignment.

Zoom and ‘Magnifying Glass’ for closeup image inspection.

Automatic reference star identification.

Automatic moving object detection and identification.

‘Track and Stack’ function to follow fast or very faint moving objects.

Access to the complete MPC database of orbital elements (MPCOrb).

Access to new-generation star catalogs (PPMXL, URAT 1, UCAC 4, and CMC-15).

Includes Internet access (Send e-mail to the MPC, download the MPCOrb databse or query reference star catalogs at VizieR).

Online help system and tutorials.
