Explanation of file found in figshare (transcripts expected count file)

I downloaded CCLE_expression_transcripts_expected_count.csv from DepMap 21Q1 Public .

I could not find a description for this file. Is this file the expected number of reads in each transcript as output by some EM algorithm?

This is the expected count for transcripts outputted by RSEM. I believe that the tool uses EM on its Bayesian model of expected counts when there is ambiguity on which read belongs to which isoform.
