sdapy.snerun.snobject.get_oac

snobject.get_oac(which='photometry', **kwargs)

Parse and add local Open Astronomical Catalog data to snobject.lc (with source name as oac)

Parameters

whichstr

which to parse: photometry or spectra

verbosebool

Enable progress report

clobberbool

Redo analysis

if which = photometry

zpfloat

zeropoint to convert flux to magnitude. zp = 23.9 for micro Jansky to AB mag zp = 48.6 for ergs/s/cm2/Hz to AB mag e.g. mab = -2.5 * log10(fv[Jy]/3631) = -2.5 * log10(fv[mJy]) + 2.5*log10(3631*1e6)

snrtfloat

SNR threshold to distinguish detection/limit

if which = spectra

rvfloat

E(B-V) to AV, default is 3.1

bin_methodstr

method used to bin spectrum

bin_sizefloat

size used to bin spectrum, in AA

savgol_orderfloat

polynomial order for savgol filter

continuum_methodstr

The function type for continumm fitting, valid functions are “scalar”, “linear”, “quadratic”, “cubic”, “poly”, and “exponential”

continuum_degreefloat

degree of polynomial when method=”poly”, for continuum fitting

Notes

• Download OAC photometry or spectra file in advance, with snobject.query_oac.

• The OAC photometry file will be read as pandas.dataframe, and added to snobject.lc with snobject.add_lc. Then snobject.add_flux or snobject.add_mag will be called if mag or flux items are missing.

• The OAC spectra file will be read and pre-processed by specline_handler.handle_spectra

• The OAC data are open public, and no registrations are needed in advance.
