This page documents the EAS ground calibration values. The first two sections present the deflector ratios applied,
elevation resolution, peak elevation and geometric factors for 32 anodes, respectively, for EAS1 and EAS2
sensors. Section 3 shows the formula used to calculate the quantum efficiencies and the table shows energy
table and quantum efficiencies. Same energy table has been used for both EAS1 and EAS2.
Elevation values correspond to sensor look directions.

Energy/Quantum efficiencies are calculated using below formula:
QE = -0.0214*alog10(Energy)^3 + 0.074*alog10(Energy)^2 - 0.0594*alog10(Energy) + 0.8875
Same Energy table was used for both EAS1 and EAS2 sensors during ground calibration work.
Below table shows the energies and corresponding quantum efficiencies used in ground calibrations.

Anodes 23 to 26 were affected by (noise) in the ground calibrations and these have been corrected by linear interpolation
along elevations. These corrected GF values are used in further calibrating for in-flight elevation values..
