ztftarget

ZTF target base tools

Description

This modules enables you to use ZTF data at the target level. It is based on the (ztfquery)[https://github.com/MickaelRigault/ztfquery] module.

Installation

git clone https://github.com/MickaelRigault/ztftarget.git
cd ztftarget
python setup.py install

Usage (OUTDATED)

This assumes that you already have a setup and running ztfquery installation and that you have access to the marshal (from ztfquery import marshal).

from ztftarget import target
t = target.ZTFTarget.from_name('ZTF20abupbub')
t.show()

if a target has several spectra, these are all shown. See the matching-color top-ticks.

A ZTFTarget has basic information such as redshift (t.z and t.zerr), coordinates (t.radec) and classification (t.classification). When loading the instance with the from_name() classmethod these parameters are loaded from your local storage of the marshal sources (ztfquery.marshal.MarchalAccess.load_local()).

In addition ZTFTarget has a lightcurve (t.lightcurve) and spectra (t.spectra). Lightcurve and spectra are downloaded automatically if you do not have them stored locally already.

All have set methods (e.g., t.set_coordinates(ra, dec) or t.set_lightcurve(dataframe)).

Component details

The target Lightcurve and spectra are registed as t.lightcurve and t.spectra, which are ztftarget.ZTFLightCurve and ztftarget.ZTFSpectra object respectively.

ztftarget.ZTFLightCurve is a wrapper around a single dataframe accessible as ztftarget.ZTFLightCurve.data
ztftarget.ZTFSpectra is a derived from pyifu.spectroscopy.Spectrum and has methods likes show(), sythesize_photometry() etc.
