Statistics

List of arguments

The list of arguments for accessing statistics can be found at https://fink-portal.org/api/v1/stats.

The statistics page makes use of the REST API. If you want to further explore Fink statistics, get numbers for a talk, or create your own dashboard based on Fink data, you can do all of these yourself using the REST API. Here is an example using Python:

import io
import requests
import pandas as pd

# get stats for all the year 2021
r = requests.post(
  "https://fink-portal.org/api/v1/statistics",
  json={
    "date": "2021",
    "output-format": "json"
  }
)

# Format output in a DataFrame
pdf = pd.read_json(io.BytesIO(r.content))

Each row is an observinng night. Note date can be either a given night (YYYYMMDD), month (YYYYMM), year (YYYY), or all observing night (empty string). The schema of the dataframe is the following:

Key Description
key:key Observation date in the form ztf_YYYYMMDD
basic:raw Number of alerts received
basic:sci Number of alerts processed (passing quality cuts)
basic:n_g Number of measurements in the g band
basic:n_r Number of measurements in the r band
basic:exposures Number of exposures (30 seconds)
basic:fields Number of fields visited
class:simbad_tot Number of alerts with a counterpart in SIMBAD
class:simbad_gal Number of alerts with a close-by candidate host-galaxy in SIMBAD
class:Solar System MPC Number of alerts with a counterpart in MPC (SSO)
class:SN candidate Number of alerts classified as SN by Fink
class:Early SN Ia candidate Number of alerts classified as early SN Ia by Fink
class:Kilonova candidate Number of alerts classified as Kilonova by Fink
class:Microlensing candidate Number of alerts classified as Microlensing by Fink
class:Solar System candidate Number of alerts classified as SSO candidates by Fink
class:Tracklet Number of alerts classified as satellite glints or space debris by Fink
class:Unknown Number of alerts without classification

All other fields starting with class: are crossmatch from the SIMBAD database.
