texture for IBL

Anymatter

hi there,

im confused with the texture usage for IBL lighting in poser pro 2014. there are 2 types of images located in texture folders, as attached below.

 

in poser default state( the 1st time when starting the program), they is 1light which uses the 1st type (panoramic) for image based lighting. However, all lighting presets in light library( hdrvfx, ibl ambient occlusion etc) use the 2nd type(spherical) instead.... im confused. so which type is the best for poser ibl ligthing??
