qqnormWin: Normal QQ plot for 'CMBWindow'

In frycast/rcosmo: Cosmic Microwave Background Data Analysis

Normal QQ plot for CMBWindow

Description

This function is a modification of standard qqnorm functions to work with CMBWindow regions.

Usage

qqnormWin(cmbdf, win, intensities = "I")

Arguments

cmbdf	A CMBDataFrame.
win	A CMBWindow
intensities	A CMBDataFrame column with measured values.

Details

qqnormWin returns a normal QQ plot of for the specified CMBDataFrame column intensities and CMBWindow region. The function automatically adds a line of a “theoretical” normal quantile-quantile plot.

Value

A list with quantile components x and y and a normal QQ plot with QQ line

Examples

## Download the map first
# downloadCMBMap(foreground = "smica", nside = 1024)
# df <- CMBDataFrame("CMB_map_smica1024.fits")
# cmbdf <- sampleCMB(df, sample.size = 1000)

# win1 <- CMBWindow(theta = c(0,pi/2,pi/2), phi = c(0,0,pi/2))
# qqnormWin(cmbdf, win1)
