def lsst.shapelet.tractor.integrateNormalizedFluxes | ( | maxRadius = 20.0 , |
|
nSteps = 5000 |
|||
) |
After normalizing by surface brightness at r=1 r_e, integrate the profiles to compare relative fluxes between the true profiles and their approximations.
[in] | maxRadius | Maximum radius to integrate the profile, in units of r_e. |
[in] | nSteps | Number of concrete points at which to evaluate the profile to do the integration (we just use the trapezoidal rule). |

def lsst.shapelet.tractor.plotSuite | ( | doComponents = False | ) |
Plot all the profiles defined in this module together: true exp and dev, the SDSS softended/truncated lux and luv, and the multi-Gaussian approximations to all of these. To plot the individual Gaussians that form the multi-Gaussian approximations, pass doComponents=True. Returns a tuple of (figure, axes), where 'figure' is the matplotlib figure that contains the plot, and axes is a 2x4 NumPy array of matplotlib axes objects

def lsst.shapelet.tractor.registerRadialProfiles | ( | ) |
Register the pickled profiles in the data directory with the RadialProfile singleton registry. This should only be called at import time by this module; it's only a function to avoid polluting the module namespace with all the local variables used here.
