entropyCMB: CMB Entropy
In rcosmo: Cosmic Microwave Background Data Analysis

Description Usage Arguments Value References Examples

This function returns an estimated entropy for the specified CMBDataFrame column intensities and CMBWindow region. The functions employs the function entropy and uses histogram counts of intensities for computations. All arguments of the standard entropy can be used.

1	entropyCMB(cmbdf, win, intensities = "I", method)

`cmbdf`	A `CMBDataFrame`.
`win`	A `CMBWindow`
`intensities`	A `CMBDataFrame` column with measured values.
`method`	A method to estimate entropy, see entropy
