Footprint

class rubin_sim.scheduler.utils.Footprint(mjd_start, sun_ra_start=0, nside=32, filters={'g': 1, 'i': 3, 'r': 2, 'u': 0, 'y': 5, 'z': 4}, period=365.25, step_func=None)

Bases: object

An object to compute the desired survey footprint at a given time

Parameters:

mjd_startfloat

The MJD the survey starts on

sun_ra_startfloat

The RA of the sun at the start of the survey (radians)

Methods Summary

__call__(mjd[, array, norm])	Returns:
arr2struc(inarr)	take an array and convert it to labled struc array
estimate_counts(mjd[, nvisits, fov_area])	Estimate the counts we'll get after some time and visits
get_footprint(filtername)
set_footprint(filtername, values)

Methods Documentation

__call__(mjd, array=False, norm=True)

Returns:

a numpy array with the normalized number of observations that should be at each HEALpix.

Multiply by the number of HEALpix observations (all filters), to convert to the number of observations

desired.

arr2struc(inarr)

take an array and convert it to labled struc array

estimate_counts(mjd, nvisits=2200000.0, fov_area=9.6)

Estimate the counts we’ll get after some time and visits

get_footprint(filtername)

set_footprint(filtername, values)
