We report on the X-ray spectral behavior within the steady states of GRS 1915+105 .
Our work is based on the full data set on the source obtained using the Proportional Counter Array on the Rossi X-ray Timing Explorer and 15 GHz radio data obtained using the Ryle Telescope .
The steady observations within the X-ray data set naturally separated into two regions in the color-color diagram and we refer to them as steady-soft and steady-hard .
GRS 1915+105 displays significant curvature in the coronal component in both the soft and hard data within the RXTE /PCA bandpass .
A majority of the steady-soft observations displays a roughly constant inner disk radius ( R _ { in } ) , while the steady-hard observations display an evolving disk truncation which is correlated to the mass accretion rate through the disk .
The disk flux and coronal flux are strongly correlated in steady-hard observations and very weakly correlated in the steady-soft observations .
Within the steady-hard observations we observe two particular circumstances when there are correlations between the coronal X-ray flux and the radio flux with log slopes \eta \sim 0.68 \pm 0.35 and \eta \sim 1.12 \pm 0.13 .
They are consistent with the upper and lower tracks of , respectively .
A comparison of model parameters to the state definitions show that almost all steady-soft observations match the criteria of either thermal or steep power law state , while a large portion of the steady-hard observations match the hard state criteria when the disk fraction constraint is neglected .
