Getting Started

Using `iDiffuse` to calculate expected photometric precisions

Import necessary packages

from importlib import reload
import os
import glob2
import pandas as pd
import numpy as np
import sys
import hpfspec
import hpfspecmatch

Read in library

Make sure there is a folder called ../library/20201008_specmatch_nir/

Download data from here and unzip in the ../library/ folder

insert dropbox link It should be structured:
../library/20201008_specmatch_nir/20201008_specmatch_nir.csv
../library/20201008_specmatch_nir/FITS/

# List of fitsfiles
LIBRARY_DIR = '../library/20201008_specmatch_nir/'

library_fitsfiles = glob2.glob(LIBRARY_DIR+'FITS/*/*.fits')
library_fitsfiles # should be many fitsfiles

# Read in all files as a HPFSpecList object
HLS = hpfspec.HPFSpecList(filelist=library_fitsfiles)

# Read in required information on all of the
# This has the Teff, Fe/H, and logg for all of the stars
# OBJECT_ID is the HPF name of the star
df_lib = pd.read_csv(LIBRARY_DIR+'20201008_specmatch_nir.csv')
df_lib

Read in example target

# Target data
targetfilename = '../input/toi1468/Slope-20200129T015117_R01.optimal.fits'
Htarget = hpfspec.HPFSpectrum(targetfilename,targetname='UCAC4 547-002110')

# Reference data
Hrefs   = HLS.splist
