Showing the ALBUS estimates of IFRM and STEC for the “D2” observation. Left panel: the estimated IFRM for all 10 models. Center panel: the estimated IFRM for the six stable models. Note that the estimate for the G01 model is higher than the others and closely matches the observed lunar values. Right panel: the STEC for the six stable models. Note that although all stable models have similar values of STEC, the ALBUS code estimates different values of IFRM.
