1° indicates the high flat tone. If ° appears after any other tones, it signifies a changed tone and that the word is to be pronounced as 1°, but 1° is not the original/normal tone of the word. Similar to °, if * appears after any tones apart from tone 2, it indicates that the word is to be pronounced as tone 2, but tone 2 is not the original/normal tone of the word.
