…kimming (AliceO2Group#3939) * PWGHF: Implent the possibility to apply proton PID for baryons in HF finding * Please consider the following formatting changes * Restore author removed by mistake * Remove all MY_DEBUG instances * Restore line wrongly deleted * Fallback to fill PVrefit table for all tracks at once to avoid crash due to tracks with no collision * Move initialisation of whichHypo * Add check on hasTPC and hasTOF in case of single detector PID * Remove extra slash --------- Co-authored-by: ALICE Action Bot <[email protected]>
