| Summary | 0000884: Virtual Observatory Integration - SAMP communication | ||||
| Description | With the addition of the right click for Sinbad, NED, HyperLeda information CdC is part way to being a Virtual Observatory (VO) Application. My next suggestion is that CdC be integrated with the VO in the other direction i.e you find an object in the VO and CdC moves to that position. This would then allow you to slew your telescope to the same position automatically. I beleive the way to do this is to use the VO standard communication protocol SAMP ( Simple Application Message Protocol). This allows one VO application to broadcast information to another VO appliactation via the SAMP hub. This includes sending the co-ordinates of an object from the SAMP enabled VO application such as Alsdin or Topcat to another application such as CdC if this is implimented. A couple of clicks should allow you to slew your telescope to any VO target visible. As an addition images can also be sent the same way - this would allow you to tramsmit any of the millions of images from the VO to CdC as an extension to the exsisting DSS images. This includes all the Hubble images as well as those from other telescopes. | ||||

| Additional Information | Various information on SAMP is available in the VO pages on the internet. Protocol is at http://www.ivoa.net/Documents/SAMP/20110512/WD-SAMP-1.3-20110512.pdf Aladin will broadcast images though this is not in the FAQ. ( Confirmed with DS9 following Patrick's suggestion). Aladin broadcasts every position clicked on - how do we get CdC to respond only to desired positions ? If a number of widely spaced positions are sent and the telescope follows them it could be rather busy. M. Taylor (m.b.taylor@bristol.ac.uk) T. Boch (boch@astro.u-strasbg.fr) authors of the document above may be willing to help - they have answered a couple of questions on the VO for me. | ||||

Code revision 2585 to 2603 implement the SAMP protocol in CdC: http://sourceforge.net/p/skychart/code/2585/ This will be available with next Monday beta version. Here a few information until I write the documentation page. It can send and receive position click, FITS images, VO tables, VO tables row selections. I not make an option to automatically move the telescope after a click in Aladin. But this is very easy to do as the object is automatically selected in CdC. Just click in Aladin, then click the Goto button in CdC. If CdC do not include the object, just send first the table from Aladin. An option allow to keep the tables and images received from SAMP after disconnecting from the hub. This allow to make a complex data selection using Topcat for example and take the data offline for use with CdC at the telescope. The following screen shot show CdC in action with Topcat: http://www.ap-i.net/skychart/_media/en/screenshot/x003_cdc_topcat_hr.jpg The sequence to get this result is: - Use the CdC VO catalog feature to get a VO table with the XHIP catalog data required to make an Hertzsprung–Russell diagram of the Hyades area. - Send the table to Topcat using SAMP. - In Topcat, make the HR plot with absolute V as a function of B-V. - In the Topcat plot, make a subset with a selection of the red giants branch. - Send the row selection subset to Skychart using SAMP, this mark the giants in green on the chart. - Click on Aldebaran in Skychart, this send a single row selection to Topcat. It highlight the Aldebaran position in the HR plot and in the table browser. Thank you to make this suggestion, I think I really like it :-) |
