gammaray {faraway}

Xray decay from a gamma ray burst

Description

The X-ray decay light curve of Gamma ray burst 050525a obtained with the X-Ray Telescope (XRT) on board the Swift satellite. The dataset has 63 brightness measurements in the 0.4-4.5 keV spectral band at times ranging from 2 minutes to 5 days after the burst.

Format

A data frame with 63 observations on the following 3 variables.

time

in seconds since burst

flux

X-ray flux in units of 10^-11 erg/cm2/s, 2-10 keV

error

measurement error of the flux based on detector signal-to-noise values
