MoObjSlicer¶

class rubin_sim.maf.slicers.MoObjSlicer(h_range=None, verbose=True, badval=0)¶

Slice moving object _observations_, per object and optionally clone/per H value.

Iteration over the MoObjSlicer will go as: * iterate over each orbit; * if Hrange is not None, for each orbit, iterate over Hrange.

Parameters:

h_rangenumpy.ndarray or None: The H values to clone the orbital parameters over. If Hrange is None, will not clone orbits.

Methods Summary

`read_obs`(obs_file)	Read observations of the solar system objects (such as created by sims_movingObjects).
`read_orbits`(orbit_file[, delim, skiprows])
`setup_slicer`(orbit_file[, delim, skiprows, ...])	Set up the slicer and read orbit_file and obs_file from disk.
`subset_obs`([pandas_constraint])	Choose a subset of all the observations, such as those in a particular time period.

Methods Documentation

read_obs(obs_file)¶

Read observations of the solar system objects (such as created by sims_movingObjects).

Parameters:

setup_slicer(orbit_file, delim=None, skiprows=None, obs_file=None)¶

Set up the slicer and read orbit_file and obs_file from disk.

Sets self.orbits (with orbit parameters), self.all_obs, and self.obs self.orbit_file and self.obs_file

Parameters:

orbit_filestr: The file containing the orbit information. This is necessary, in order to be able to generate plots.
obs_filestr, optional: The file containing the observations of each object, optional. If not provided (default, None), then the slicer will not be able to ‘slice’, but can still plot.

subset_obs(pandas_constraint=None)¶: Choose a subset of all the observations, such as those in a particular time period.
