C2RCC results straight line

[sjhong]

After I apply C2RCC on S2 data, it results straight line on images.
Pixel values change quickly. And because of these changed pixels, the image appears to be divided into 4 regions.

Is this just a bad result or meaning something else?
If this is wrong result, how can I fix it?
Results and processes are described below.

SNAP: SNAP 8.0.0
Data: S2B_MSIL1C_20211001T020649_N0301_R103_T52SDD_20211001T034236
Process:

1. Optical - Geomtric - S2 Resamplig Processor (resolution 10 m)
2. C2RCC - S2-MSI
   Input of C2RCC was MSI L1C product only. I didn’t input any other optional arguments, like, azone and air pressure. I didn’t change Processing Parameters.
   Outputs of C2RCC are 1) TOA reflectances, 2) normalized water leaving relfectances

Result:

Original RGB Image

Band: rhown_B2. colour ramp: derived from gradient_8_colors

Band: rhown_B3. colour ramp: derived from gradient_8_colors

Band Math: rhown_B2 / rhown_B3. colour ramp: derived from gradient_8_colors

Ooops. Right after I wrote this qustion, I found this.
The problem is because of the way the sensor taking pictures, I guess.

I think I should take this into account.
Is there any good tips for this?

The stripes are known and in the thread a way to remove them is provided.

Also here is some discussion about it.

How to get a chlorophyll-a product without sunglint?

Hi, I processed your product and try to apply some L1 and Idepix flags before processing with C2RCC. The quality did not improve a lot, but it looks better than your scene above. I attach it here. Idepix or C2RCC do not find invalid pixels related to the stripes, so values should be considered right. But I think you should try to compare with in situ data or other satellite products (maybe Landsat can help?) and see if values make sense. I still do not know how homogenise the scene, maybe it is…

But the stripes are not (or not only) from sunglint. These are the camera borders. And for this problem there is no solution yet. At least as far as I know. But I actually wonder why there is no correction for this yet.
