Spearman’s rank correlation coefficients ρ between the ASM counts and the soft photon index Γ1
| Energy band [keV] | 1.5−12 | 1.5−3.0 | 3.0−5.0 | 5.0−12 |

||||
| ρ (Γ1 < 2.7) | 0.77 | 0.81 | 0.76 | 0.62 |
| ρ (Γ1 > 2.7) | − 0.60 | − 0.54 | − 0.55 | − 0.68 |
Notes.Values of Γ1 from pointed RXTE observations; ρ calculated for the cases Γ1 < 2.7 and Γ1 > 2.7 in the three individual ASM bands.
