Base Resistor in Bandgap

I have noticed that in Bandgap circuits in a BiCMOS technology they add a base resitor to one of the transistors. What is the function of this resistor? The configuration is shown in the figure attached.

YOU CAN ADJ THE RES ,AND YOU WILL GET THE BETTER TEMP COMP
 

Re: Base Resistor in Bandgap

Isn't the temperature coefficient of the PTAT current controlled by the other 2 resistors? What temperature coefficient does the base resistor improve?
