STM32F103C8 internal Temp sensor on which channel? ADCx_IN16 or ADC1_IN18

Hireading the ref manual of the STM32F103C8, it says in chapter 11.10 that the temp sensor is internally connected to ADCx_IN16. In figure 39, it says that the temp sensor is connected to ADC1_IN18.I reckon that this is a simple typo, or do I miss an...
