Differential rotation for two populations of sunspots

Sidereal rotation rates for two populations of sunspot groups: small short-lived groups (SSGs) and large long-lived groups (LLGs) as shown in Figure 7 in Nagovitsyn, Y. A., Pevtsov, A.A.,Osipova, A.A.: 2018, “Two Populations of Sunspots: Differential Rotation“, Astronomy Letters, 44, No. 3, pp. 229–238, DOI: 10.1134/S1063773718020056

本数据集包含两类太阳黑子群的恒星自转速率：小型短寿命群（Small Short-lived Groups, SSGs）与大型长寿命群（Large Long-lived Groups, LLGs），相关内容详见Nagovitsyn Y.A.、Pevtsov A.A.、Osipova A.A.于2018年发表在《天文学快报》（Astronomy Letters）第44卷第3期第229至238页的论文《太阳黑子的两类族群：较差自转》（原论文标题："Two Populations of Sunspots: Differential Rotation"），DOI编号为10.1134/S1063773718020056，该数据集的相关内容可见该文献中的图7。
