Notes. The table presents the sub-type reclassification from the ZTF DR2 sample. The DR2 Sub-type column lists the original classifications from the DR2 typing effort, with the numbers in parentheses indicating the initial count of objects in each class. The Re-classification Results column shows the outcome of a visual inspection, with the numbers in each resulting sub-type representing the changes from the initial DR2 classification in that row. For example, 18 objects initially classified as 91T-like have been reclassified as follows: 9 as 99a-like, 2 as normal, and 1 as Ia-unclear. The number of events in the final sample after removal of host contaminated events is given in Table 3.
