There is no dip in the corrected FSC curve in the job FSC validation

Hi, all!
I have read the introduction of FSC in this forum. I knew the nomask, spherical, loose, tight, corrected FSC. I was wondering that why some of the corrected FSC curve didn’t have a dip dut to phase randomization in my FSC validation jobs.

Sorry. There was a typing-error. “due to phase randomization” not “dut to”. Thank you!
