Raw data short1 unzip error

Hello, I found that the short1.zip download can not be unzipped by unzip or jar. When it is unzipped by jar, I got a CRCs do not match error.

It seems this zip file is broken. I will need to re-upload. Are the other zip files working properly?

Thanks for your reply and thanks for uploading the short1.zip again. Yes, the other zip files working properly.

And, for the raw data, how do we know the digital gain?

@gmengusthk The data has been re-uploaded. Can you check that.

For the digital gain, we use the exposure ratio between the long and short.

Thanks! Does the exposure ratio mean that the mean value of the long image divided by the mean value of the short image?

It is the exposure time. Can be read from the .ARW file.
