Daniel Soper’s sample size calculation tool Number of observed variables

Hi!

Would anyone help me?

1. While using Daniel Soper’s sample size calculation tool (https://www.danielsoper.com/statcalc/calculator.aspx?id=89), is the "number of observed variables," equal to the number of indicators in the model, or is it equal to the number of indicators + the number of dependant variables?

 

2. In a model with 3 latent variables, 1 dependent variable, and 18 indicators, what would be the number of observed variables in Daniel Soper’s sample size calculation tool?
