sdapy.snerun.snobject.get_external_phot

snobject.get_external_phot(filename, source='myfavour', **kwargs)

Parse and add user defined photometric data to snobject.lc

Parameters

filenamestr

path of the photometric file

sourcestr

source name, if None will add flux column for all data

magkeystr

meta key for AB magnitude

emagkeystr

meta key for magnitude error

limmagkeystr

meta key for limiting magnitude

fluxkeystr

meta key for flux, unit in 1e-6 Jy

efluxkeystr

meta key for flux error

filterkeystr

meta key for filters

jdkeystr

meta key for julian date

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

Notes

After reading filename into pandas.dataframe, snobject.add_lc will be called to add the dataframe into snobject.lc, and if mag or flux item missed, snobject.add_flux or snobject.add_mag will be called correspondingly.
