A new stellar database of the Ca II Triplet, which serves as an indicator for characterizing the chromospheric activity of stars. It includes R, R+ index for Ca II IRT, stellar parameters and other valuable information, the uncertainties of the index also be given. More detail about it please read our paper. In version 1.0, there are a very small number of entries (66) that lack Gaia magnitude data. Upon investigation, this is due to Gaia having two different sourceid for the same target. This has been corrected. Additionally, the mrt format file for this database has been added. The provided manuscript is the version at the time of acceptance. Please refer to the formal published article for accuracy.
