We have assembled an atlas of line profiles of the Paschen Delta ( P \delta ) line at 10 049 \AA for the use of stellar modelling .
For a few stars we have substituted the Paschen Gamma ( P \gamma ) line at 10 938 \AA because the P \delta line blends with other features .
Most of the targets are standard stars of spectral types from B to M. A few metal-poor stars have been included .
For many of the stars we have also observed the Hydrogen Alpha ( H \alpha ) line so as to compare the profiles of lines originating from the meta-stable n = 2 level with lines originating from the n = 3 level .
The greatest difference in line profile is found for high luminosity and cool stars where the departures from LTE in the population of the n = 2 level is expected to be the greatest . For a few stars , sample line profiles have been calculated in the LTE approximation to demonstrate the usefulness of the tabulated and displayed catalogue .
