The brief

Normal Sudoku rules apply.

1-5-9: Each digit in column 1 indexes the 1 in its row (i.e if R3C1=4 then R3C4=1). The same rule applies to column 5 digits indexing 5 in its row, and column 9 digits indexing 9 in its row.

A black dot between cells indicates cell values with a 2:1 ratio. ALL BLACK DOTS ARE GIVEN.

Digits along each thermometer must increase starting from the bulb end.
