The main address at the moment is:


  • In order to access the server you need a so called "hashtag" which is an autorization key. In order to get one you need to ask Lukasz Wyrzykowski and report to him also

the lon,lat of your observatory and list of filters you have

Calibration of your photometric data

The main url for calibration of your sextractor catalogs is

You can also do that from the command line using HTTP POST protocol

curl -F matchDist=2 -F EventID='ivo://110610' -F sexCat="@test/;" 
     -F "hashtag=XXXX" -F "MJD=2" -F "matchDist=2"
     -F  EventID='ivo://110610' -F expTime=1 -F noPlot=1
     -F forceFilter=no -F dryRun=1 -F outputFormat=json ""

Parameters of the

  • matchDist -- matching radius in arcseconds
  • hashtag -- your authorization key
  • MJD -- mjd of the observations
  • expTime -- exposure time
  • comment -- comments
  • EventID -- the ivorn of the alert
  • dryRun -- the value of 1 allows you to check the results of the calibration without inserting anything into our DB
  • forceFilter -- "no" means that the calibration will be fully automated. But You can also specify APASS/V if you want to calibrate using a particular survey/filter
  • sexCat -- that's the Sextractor catalog you are trying to submit
  • outputFormat -- at the moment the only allowed values are json and html

It is important that you upload the data for the alerts which are in the database (e.g. which are listed here ). If the alert is not in our DB, you can insert it
