VizieR Online Data Catalog: R- and I-band photometry of 506 asteroids with CNEOST (Yeh+, 2020)

We used the China Near-Earth Object Survey Telescope (CNEOST) to conduct the survey. The CNEOST is a 1.2m telescope located at the XuYi station. Two surveys were conducted, using 90s exposures.

The first survey was carried in 2017 February 26 to March 2, which covered a total survey area of ~45°² close to the ecliptic plane. We continuously scanned on four main fields in a cadence of ~8minutes using the R band for the first four nights and another additional field was added in the last night for the follow-up observation of near-Earth asteroids of the other proposal.

The second survey was conducted in 2018 March 8, 9, 11, and 12, which had a total survey area of ~60°2. In this survey, six fields were repeatedly observed in a cadence of ~10 minutes using the I-band and, moreover, an extra field was added in the last two nights to follow up other targets of another proposal.
