Abaqus - Contact Output (CSLIP)

Hello everyone,

I am working on some contact analysis in Abaqus 2018.. As part of the simulation i would like to see the results for CSLIP in the output.

But there is no CSLIP Keyword available in the results request. Instead there are CSLIP1 and CSLIP2 in the output request..

Please let me know if there is CSLIP output available in abaqus or not?

Also what is the difference between CSLIP1 and CSLIP2
