Unable to download GazeCapture dataset via wget (receiving HTML instead of .tar)

I am trying to download the GazeCapture dataset using the provided wget command, but I am not receiving the actual dataset file.

I ran the following command on macOS: wget -O gazecapture.tar "https://gazecapture.csail.mit.edu/dataset.php?email=***&hash=***"

The request returns HTTP 200 OK, but the downloaded file is only 31 bytes and is identified as an HTML document rather than a .tar archive. It appears to be a webpage response instead of the dataset itself.

I suspect this may be related to authentication, session cookies, or browser-based confirmation requirements. However, the documentation suggests that wget should work directly.

For reference, the email address I used to request the download link is sarang0116@mail.ulsan.ac.kr
