IRQ number of TIM11 on STM32F103FxF,G

The datasheet for 'F103F,G parts show additional timers, e.g. TIM11, not present on the earlier parts, e.g. 'F103RB.  Where is documentation that specifies the IRQ number for these timers?

The datasheet says the NVIC has 60 interrupt channels, yet the datasheet for STM32F103xC, STM32F103xD and STM32F103xE that does not have these timers also shows 60 interrupt channels, which suggests these timers must share interrupt vectors with something else.

I would rather ST put the IRQ numbers in the datasheet for the part.  Looking at code files for documentation seems backwards.

It is in the reference manual, the code was a quick place to look. Page 193, Table 62
