Simulating an Untargeted Survey

Creating an Untargeted Survey

For an untargeted survey search, use the following example:

from __future__ import print_function
import surveySim
from astropy import units as u
snls=surveySim.survey(name='SNLS',snTypes=['Ia','Ib','Ic','IIP'],zmin=.1,zmax=1.1,dz=.05)
snls.area=4*u.deg**2
snls.cadence=4*u.day
snls.magLimits=[24]
snls.filters=['sdss::i']
snls.surveyLength=2.08*u.year
snls.unTargetedSurvey(zpsys='vega')
snls.verbose=True
print(snls)
snls.plotHist('sdss::i','Ia',savePlot=True,showPlot=False)#,showPlot=False,savePlot=True)

Out:

Survey Name:SNLS
             Length: 2.08 Years
             Cadence: 4.0 Days
             Area: 4.0 Square Degrees
             Redshift Range: 0.1-->1.1

             Lower Bound Ia:765.06
             Upper Bound Ic:464.07
             Lower Bound Ic:232.03
             Upper Bound Ib:464.07
             Lower Bound Ib:232.03
             Upper Bound IIP:16.51
             Lower Bound IIP:8.25

             Total Ia Upper Bound:1530.13
             Total Ia Lower Bound:765.06
             Total CC Upper Bound:944.64
             Total CC Lower Bound:472.32

             Total Lower Bound:1237.39
             Total Upper Bound:2474.77

Plot the Results in a Histogram

You can directly plot a specific band from the result Dictionary:

snls.plotHist('sdss::i','Ia')
