论文摘要
罗马精确的太阳光度计望远镜（罗马/PSPT）是一种从事精确太阳光度法的地面望远镜。 It has a 27-year database of full-disk images of the photosphere and chromosphere beginning in 1996 and continuing to 2022. The solar images have been obtained daily, weather permitting, with approximately 2 arcsec/pixel scale in Ca II K line at 393.3 nm, G-band at 430.6 nm, and continuum in the blue and red parts of the spectrum at 409.4 nm and 607.2 nm, respectively.还在535.7 nm的绿色连续体进行了定期观察，约有18个月。自从第一灯以来，罗马/PSPT操作一直致力于了解短期和长期太阳辐照度变化的来源，分别从一分钟到几个月，从一年到几个太阳能周期。然而，罗马/PSPT数据也有助于研究其他各种主题，包括太阳能磁盘特征的光度特性以及由色球环网络所表现出的超晶体的光度特性。此外，它们在允许连接一系列历史和现代全盘太阳能观察（尤其是CA II K线数据）方面一直是独一无二的。在这里，我们提供了罗马/PSPT望远镜的概述以及从第一光到现在，跨太阳能循环23-25进行的太阳能监视。我们还简要描述了罗马/PSPT数据获得的主要结果，并概述了涵盖1996 - 2022年期间的整个观测值的新结果。
The Rome Precision Solar Photometric Telescope (Rome/PSPT) is a ground-based telescope engaged in precision solar photometry. It has a 27-year database of full-disk images of the photosphere and chromosphere beginning in 1996 and continuing to 2022. The solar images have been obtained daily, weather permitting, with approximately 2 arcsec/pixel scale in Ca II K line at 393.3 nm, G-band at 430.6 nm, and continuum in the blue and red parts of the spectrum at 409.4 nm and 607.2 nm, respectively. Regular observations were also performed at the green continuum at 535.7 nm for a period of about 18 months. Since the first-light, Rome/PSPT operations have been directed at understanding the source of short-and long-term solar irradiance changes, spanning from one minute to several months, and from one year to a few solar cycles, respectively. However, Rome/PSPT data have also served to study a variety of other topics, including the photometric properties of solar disk features and of the supergranulation manifested by the chromospheric network. Moreover, they have been unique in allowing to connect series of historical and modern full-disk solar observations, especially the Ca II K line data. Here, we provide an overview of the Rome/PSPT telescope and of the solar monitoring carried out with it from its first light to the present, across solar cycles 23-25. We also briefly describe the main results achieved with Rome/PSPT data, and give an overview of new results being derived with the whole time series of observations covering the period 1996-2022.
