“…Nonetheless, filter systems may differ among several telescopes. For instance, telescopes at Xinglong (Huang et al 2012;Fan et al 2016;Bai et al 2018) and Weihai (Hu et al 2014;Gao et al 2016) in China use the Johnson-Cousins filter system, while telescopes at Wendelstein Observatory in Germany (Hopp et al 2014;Steuer et al 2021) and Nanshan in China utilize the SDSS ¢ ¢ ¢ ¢ ¢ u g r i z system. Other amateur telescopes rely on RGB filters or white band (refer to Table 1).…”

We report the confirmation of a sub-Saturn-size exoplanet, TOI-1194 b with a mass about 0.456-0.051 +0.055 MJ, and a very low mass companion star with a mass of about 96.47±1.5 MJ, TOI-1251 B. Exoplanet candidates provided by the Transiting Exoplanet Survey Satellite (TESS) are suitable for further follow-up observations by ground-based telescopes with small and medium apertures. The analysis is performed based on data from several telescopes worldwide, including telescopes in the Sino-German multi-band photometric campaign, which aimed at confirming TESS Objects of Interest (TOIs) using ground-based small-aperture and medium-aperture telescopes, especially for long-period targets. TOI-1194 b is confirmed based on the consistent periodic transits depths from the multiband photometric data. We measure an orbital period of 2.310644±0.000001d, and radius is 0.767-0.041 +0.045RJ, and amplitude of RV curve is 69.36-7.31 +7.90 m/s. TOI-1251 B is confirmed based on the multi-band photometric and high-resolution spectroscopic data, whose orbiting period is 5.963054-0.000001 +0.000002d, the radius is 0.947-0.033 +0.035RJ, and amplitude of RV curve is 9848.87-40.08 +41.86m/s.
