High Precision Calibration Pairs for Southern Lucky Imaging

TL;DR

This paper provides a catalog of 50 well-calibrated double star pairs across the southern sky, enabling precise instrument calibration for lucky imaging observations.

Contribution

It introduces a new set of calibration pairs with milli-arcsecond and milli-degree accuracy for southern sky lucky imaging.

Findings

50 calibration pairs identified with high positional accuracy

Pairs are evenly distributed over the southern sky

Facilitates improved calibration for lucky imaging instruments

Abstract

Accurate measures of double stars require accurate calibration of the instrument. Here we present a list of 50 pairs, that are quasi-evenly spaced over the southern sky, and that have Separations and Position Angles accurate at the milli-arcsec, and milli-degree level. These wide angle pairs are suggested as calibration pairs for lucky imaging observations.
