摘要

我们报告了2015年至2018年间使用历史悠久的Tonantzintla Schmidt相机对九颗主带小行星（MBA）、四颗近地小行星（NEA）和一颗火星穿越小行星（MCA）进行的光度观测，这是该望远镜重新激活MBA和NEA天体测量和光度后续观测过程的一部分。该观测计划是INAOE在请求将其纳入国际小行星预警网（IAWN）时所作承诺的一部分。我们给出了这14颗小行星的光照曲线及其相应的傅立叶分析，以确定小行星的自转周期和光照曲线的亮度幅度。

PHOTOMETRIC OBSERVATIONS OF MINOR PLANETS WITH THE TONANTZINTLA SCHMIDT CAMERA I. LIGHT CURVE ANALYSIS OF MAIN-BELT AND NEAR-EARTH ASTEROIDS

We report photometric observations of nine main-belt asteroids (MBAs), four near-Earth asteroids (NEAs), and one Mars-crossing asteroid (MCA) carried out with the historical Tonantzintla Schmidt Camera between 2015 and 2018, as part of a process of reactivation of this telescope for astrometric and photometric follow-up observations of MBAs and NEAs. This observational program is part of the commitment made by INAOE when requesting its inclusion in the International Asteroid Warning Network (IAWN). We present the light curves of these 14 asteroids and their corresponding Fourier analyses to determine the rotation period of the asteroids and the brightness amplitude of their light curves.
