Reading & tones

Schematic citation-tone diagrams from the source numbers. These are not recordings or predictions of connected speech.

Same syllable, six tones

jat一jat1onejat2—jat3—jat4—jat5—日jat6sun

Characters whose customary Unihan reading (kCantonese) is this syllable in each tone, chosen as in the tone atlas (2013 standard level, then the number of CC-CEDICT words they form), with CC-Canto 2017's meaning for that reading; a dash means no catalogue character has that reading. Checked syllables (-p, -t, -k) normally carry tones 1, 3 and 6. Character readings, not word readings; no frequency implied.
