L2 coccolith flag?

[lisenik]

Have someone ever seen the description of level2 flags? What are the criteria to put them? I am especially interested in coccolith flag. I cannot find it online. I would appreciate if someone can point me in the right direction.
Upd. I have found a piece of code in src/l2gen/setflags.c that defines it, but still there are questions.
What are these constants? Where do they come from?
141 c1 = input->coccolith[0];
142 c2 = input->coccolith[1];
143 c3 = input->coccolith[2];
144 c4 = input->coccolith[3];
145 c5 = input->coccolith[4];
146 c6 = input->coccolith[5];
147 c7 = input->coccolith[6];
148 c8 = input->coccolith[7];
