Statistical analysis of the causes of excess variance in the 21 cm signal power spectra obtained with the low-frequency array

HIGHLIGHTS

• who: Gan H. and collaborators from the (UNIVERSITY) have published the research work: Statistical analysis of the causes of excess variance in the 21 cm signal power spectra obtained with the Low-Frequency Array, in the Journal: (JOURNAL)
• what: The authors focused on the impact of gain errors the sky model and ionospheric effects on the excess variance by correlating the relevant parameters such as the gain variance over time or frequency local sidereal time (LST) diffractive scale and phase structure- function slope with the level of excess variance. The analysis shows that the excess . . .
