Abstract

We have assembled an atlas of line profiles of the Paschen Delta (P-{delta}) line at 10049{AA} for the use of stellar modelling. For a few stars we have substituted the Paschen Gamma (P-{gamma}) line at 10938{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.
