Hello,
"As a rule, the horizontal component of the field (H-component) is used for calculating the indices of geomagnetic activity and analyzing variations of the Earth’s magnetic field during magnetic storms".
Do we need to insert "the" before "indices"? There are several main indices of geomagnetic activity used all over the world and recognised by geophysicists, but the sentence says nothing about any particular indices, but just mentions their existence and application. That's why I have doubts about using "the".
Thanks
