### etable: exponential tabular model

An exponential table model. The
filename to be used should be given immediately after etable in the model
command. For example:

XSPEC12>**model** etable{mymod.mod}

uses mymod.mod as the input for the
model. XSPEC will multiply the contents of the model by –1 then take the
exponential *i.e.* this model is for calculating absorption functions. For
specifications of the table model file, see the OGIP memo 92-009 on the FITS
file format for table model files (available on the WWW or by anonymous ftp
from ftp://legacy.gsfc.nasa.gov/caldb/docs/memos.).
