EVE New Citizens Q&A

Well ive been trying to google this but cant find an answer, im trysing to find the difficulty of cosmic anomolies in ascending order, all i find is a list of the regular anomolies, from barrow to sanctum, but then there are modifiers like hidden, forlorn, etc, but whats the difficulty in ascending order from easiest to most difficult, like how hard is a hidden hideaway from a refuse, or a forlorn hideaway from a den, i know the basic cosmic anomolies, but its the modefiers i cant figure out how difficult they are in comparison to regulars.
