HETG: E0102 for Calibration

Images of combined plus/minus first-order events from MEG (top, 112.9 k-events) and HEG (bottom, 33.3 k-events) from Obsids 120, 968, and 3828.
The wavelength range shown is from 3 A (left) to 23 A (right.)

HETG: E0102 for Calibration

Introduction

The SNR E0102 is a useful calibration source for X-ray instruments (e.g., these) because of its compact size, many bright low-energy lines, and relatively constant flux and spectrum. The lack of a bright "iron forest" reduces the number of lines in the spectrum making its modeling more accurate for lower resolution detectors.
This web page has links to work using the HETG observations of E0102 to check and improve models of the E0102 spectrum.

Combined zeroth-order image, 149 k-events from ~ 270 ks of data.
