CAMELOT:

 E2V back illuminated chip  Pixel size: 3.5x13.5 µm

(0.304x0.304 arcsec)

 Size: 2148 x 2048 pix2  Field of

View: 10.4 x 10.4 arcmin2

 Filter wheel with 12 positions

and more than 60 filters available (Johnson, SDSS, Strömgren and narrow band)

 ToO observations.  „Routine‟ mode.  Long term programs.  Simultaneous or multiband

collaborations with other telescopes.

 Student practice.  Instrumentation tests.

 Photometric follow-up of planet candidates from

COROT mission.

 Observation of stellar occultations by TransNeptunian

dwarf planet candidates.

 Monitoring of blazars and quasars.  R-band photometry of M dwarfs in the CARMENES

input catalogue.

 Optical/NIR Observations of Newly Discovered X-

Ray/Gamma-ray Sources.

 Gamma-ray burst ToO observations.  …

We used the DALT

  • olKit publishing software to publish these data in the Virtual

Observatory following the Data Access Layer (DAL) protocol specifications. Incoming standard DAL requests into database specific SQL queries and then serialize the database result into VOTable responses according to the VO standard.

Future plans:  Publish all the data from 2005 (THIS SUMMER) and

  • lder…

 Publish all the narrow band filters in the SVO Filter Profiles

  • Service. SOON

 Publish the infrared data from the T elescopio Carlos Sánchez at Observatorio del T

  • eide. NEXT YEAR
