Abstract:
Physical conditions inside a supernova remnant can vary significantly
between different positions. However, typical observational data of
supernova remnants are integrated data or contemplate specific
portions of the remnant.
We study the spatial variation in the physical properties of the N49
supernova remnant based on a spectroscopic mapping of the whole
nebula.
Long-slit spectra were obtained with the slit (∼4'x1.03") aligned
along the east-west direction from 29 different positions spaced by 2"
in declination. A total of 3248 1D spectra were extracted from
sections of 2" of the 2D spectra. More than 60 emission lines in the
range 3550Å to 8920Å were measured in these spectra. Maps of the
fluxes and of intensity ratios of these emission lines were built with
a spatial resolution of 2"x2".
Description:
The fits files are bi-dimensional maps (112x29) of relative line
intensities, line fluxes, electron density, and electron temperature
of the supernova remnant N49.
