Dear colleague:
 
I'm Liu Haoyang, a fresher of EinsteinToolkit from University of Chinese Academy of Science.
 
I found that some Thorn's documents in Thorn Guide lack detailed description about their variables' function, such as "Carpet" and "ReflectionSymmetry". And it seems that access to https://carpetcode.org/ is restricted.
 
Is there any other material for such Thorns I can learn about? And how can I have access to the website of Carpet?
 
Liu Haoyang
