Dear SPMers. 

could someone clarify for me what the betas produced using time and dispersion derivatives are? Is it that the first is canonical only, the second is canonical+time, and the third is canonical+time+dispersion, OR is it canonical only, time only, and dispersion only? 

Thanks! 

Laura.
