Notes. Morphology class = classification of the light curve variability type; each class is briefly defined in Appendix A of this work. Count = number of objects in the sample with light curves falling in the corresponding category (a given object is here attributed to a single category, namely the one that best describes the dominant variability features of its light curve, although some cases may also exhibit traits of a different morphology class). c/w = number of CTTS/number of WTTS among objects in the corresponding morphology class. % tot. = percentage of objects in the sample that fall in the corresponding morphology class. % Per = percentage of objects in the corresponding morphology class which are found to be periodic.
