Fetch data from NASA/IPAC EXTRAGALACTIC DATABASE

Demo

Demo page:

Introuction

This program generates random RA(Longitude) and DEC(Latitude). It sends these parameters to NASA/IPAC EXTRAGALACTIC DATABASE and fetch the following fields from the returned result.

  • Landolt B Bandpass [µm]
  • Landolt B Aλ [mag]
  • Landolt R Bandpass [µm]
  • Landolt R Aλ [mag]
  • UKIRT K Bandpass [µm]
  • UKIRT K Aλ [mag]

You can easily change the fields that need to be fetched.

Sample input:

  • Sample = 3

Sample output:

RA DEC B[µm] B Aλ R[µm] R Aλ K[µm] K Aλ
2h59m59s 30d0m0s 0.44 0.823 0.65 0.510 2.22 0.070
15h2m32s -54d7m27s 0.44 4.133 0.65 2.561 2.22 0.352
9h49m44s 54d3m48s 0.44 0.039 0.65 0.024 2.22 0.003

Usage

  1. Choose AJAX or PHP form
  2. Enter the sample number
  3. Click the "GO GO GO" button

Note: If the sample number is set too large (i.e. larger than 100), it may take a long time to get the result depending on the Internet connection of your web server.

To fetch 1000 samples, it is recommended to fetch 100 samples 10 times, rather than to fetch 1000 samples directly.
