High Precision Calibration Pairs for Northern Lucky Imaging
Matthew B. James, Graeme L. White, Roderick R. Letchford +1
Presented here is list of 50 pairs quasi-evenly spaced over the northern sky, and that have Separations and Position Angles accurate at the milli-arcsec, and milli-degree level. Th…
High Precision Calibration Pairs for Southern Lucky Imaging
Matthew B. James, Graeme L. White, Roderick R. Letchford +1
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 h…
Comparison of Image Scale Calibration Techniques: Known Pairs, Drift Scans and Aperture Grating
Matthew B. James, Graeme L. White, Stephen G. Bosi +1
We compared several techniques for calibrating angular separation between wide (>1 arcsec) pairs. These techniques are (i) reference pair calibration using α Cen AB orbital paramet…
Measures of 62 Southern Pairs
Matthew James, Rod Letchford, Graeme L White +2
We report lucky imaging observations of 62 pairs at mid-southern declinations sourced from the WDS with separations larger than 4 arc seconds and magnitude less than 10. The measur…
