I've been asked to find out how vedic priests  pronounce the AdigAyatrI mantra (Rg-veda 3.62.10).  I've found it on a website online with accent marks and compared it to the Rg-veda (see attachment).  But I've been told that some of the svarita accents are dIrgha-svarita (i.e. a two note pronounciation medium followed by high).  

Can someone tell me which svarita accents in the mantra are dIrgha-svarita.

Thanks,
