Typo in Lesson 9 Writing your own diagnostics script

[gulcing]

In Lesson 9 Writing your own diagnostics script part of " Diagnostic computation“, it is written:

Here we have grouped the input data by variables so we loop over the variables (line 88). Following this, is a call to the function compute_diagnostic (line 93). Let’s have a look at the definition of this function in line 42 where the actual analysis on the data is done.

ESMValTool_Tutorial/_episodes/08-diagnostics.md

Line 342 in 4c08c16

After grouping and selecting data, we can read individual attributes (such as filename)

I suggest changing to "Here, we have grouped the input data by variables, so we loop over the variables (line 88). Following this is a call to the function compute_diagnostic (line 93). Let’s look at the definition of this function in line 42, where the actual analysis of the data is done."
