Abstract

This erratum corrects errors in two figures.

This article [J. Astron. Telesc. Instrum. Syst. 8(1), 011013 (2022) https://doi.org/10.1117/1.JATIS.8.1.011013] was originally published with typographical errors in Figs. 3 and 10.

Fig. 10

In Fig. 3, in the top blue block, an “approximately equal” sign should have been used instead of an equal sign. Additionally, the symbols #I and #J were confused by the authors. Therefore, the text should read Si ≈ (CLOCK- REF) for i = 1 to N instead of Si = (CLOCK #J- REF) for i=1 to N. Later in the same sentence, the text should read “clock #J” instead of “clock #I.” The corrected figure is shown here.

In Fig. 10, the legend for the green line was incorrectly written as the quantity (KGPS(1)C0)CircularT,section4. The symbol C0 is, however, C0 in the paper’s text, and the legend is incompatible with that. Therefore, the figure has been corrected to: (KGPS(1)C0)CircularT,section4. The corrected figure is shown here.

The article was corrected on 21 January 2022.
