Reading in Previously Corrected Light Curves

In this tutorial we will be reading in a light curve that we have already downloaded and corrected. If you have not done this, please see the plotting tutorial.

import elk
import numpy as np

%config InlineBackend.figure_format = "retina" # Not required, only applicable for Jupyter Notebooks

# We will also need the two classes imported
from elk.ensemble import EnsembleLC
from elk.lightcurve import BasicLightcurve

# define the path to your lightcurves
path = 'Corrected_LCs/'

# which Cluster would we like to read in
Name = "NGC 419"

c = elk.ensemble.from_fits(path + Name + "output_table.fits")

From here, we have all of the available functions of a BasicLightcurve in elk!

Let’s look at the summary table.

c.summary_table()

Table length=1

name	location	radius	log_age	has_data	n_obs	n_good_obs	which_sectors_good	n_failed_download	n_bad_quality	n_scatter_light	scattered_light_sectors	lc_lens
str7	str18	float64	float64	bool	int64	int64	str8	int64	int64	int64	str10	str12
NGC 419	23.58271, +61.1236	0.046	7.75	True	4	2	[18, 24]	0	0	2	[[25, 58]]	[1103, 1224]

Or we can plot one of the light curves

c.lcs[0].plot()

(<Figure size 640x480 with 1 Axes>,
 <Axes: title={'center': 'Lightcurve for Sector 18'}, xlabel='Time $\\rm [days]$', ylabel='Flux $[e / {\\rm s}]$'>)
