dynaspec is a simple tool for showing time series of astronomical spectra
in a 2 dimensional plot.
Spectra must be in FITS format with NAXIS = 1, and must contain the following
headers as a minimum:
CRVAL1
CRPIX1
CDELT1
JD-MID
dynaspec requires Python, with the following modules - pyfits, numpy,
matplotlib and scipy.
The directory example contains some simulated dynamic spectra:
Given these spectra as input, the following plots were generated:
# Plot dynamic spectra with defaults
./dynaspec example/*.fit
# Plot with velocity scale against 6563 Angstrom with a custom colormap
./dynaspec --velocity 6563 --cmap afmhot example/*.fit
A script for plotting 3d time series is also provided:
# Plot 3d with defaults
./dynaspec_3d example/*.fit
# Plot 3d without contour map and with custom colormap
./dynaspec_3d --nocontour --cmap gist_stern example/*.fit
