Description
Hi, when I use Projector class in leaptorch:
proj = Projector(forward_project=False, use_static=True, use_gpu=True, gpu_device=device, batch_size=batchSize)
f = proj(g)
proj.leapct.fbp(g, f0)
I found that f is in the order of 10^3, while f0 is in the order 10^(-4), is here any mistake I made? Actually I need to use f= proj(g) in my program, but the result's order is far from the order of FBP's result.

Research direction
Reproduce the shown Projector call and compare its output with leapct.fbp(g, f0), recording the observed scaling difference. Read the Projector and fbp entry points first; done means determining whether the discrepancy comes from usage or an implementation issue and clearly documenting the finding.
