Foggy Faces

Normal sudoku rules apply. Digits along a marked diagonal must not repeat. Digits separated by a black dot must be in a 1:2 ratio. Digits separated by a white dot must be consecutive. Digits along a green ‘German Whisper’ line must have a difference of at least 5. No digits along a golden ‘Nabner’ line are consecutive with any other. There is only 1 Nabner line in this puzzle. Digits along a thermometer must increase from the bulb end. Cells around a big white circle must include the digits given in the circle. (Digits increase from top right anti-clockwise) The grid is partially covered with fog, correct inputs will clear the surrounding fog (no cheating is required) No negative constraint
