Database of daily observation filesMark-I is a solar spectrophotometer located and operated at Observatorio del Teide (Tenerife, Canary Islands, Spain) that provides precise radial velocity observations of the Sun-as-a-star at the Potassium KI 7699A absorption solar line.
Observations extend from 1976 to 2013 with only summer campaigns from 1976 to 1983.
The SpaceInn Project ("Exploitation of Space Data for Innovative Helio- and Asteroseismology", www.spaceinn.eu) has been initiated by The European Helio and Asteroseismology Network (HELAS) with the mission to build on the existing European strength in the field of time-domain stellar physics. It is funded for four years (2013-2016) by the European Union under the Seventh Framework Programme (FP7).
The Mark-I Data Access Service is the results of an agreement between the CoSADIE and Spaceinn FP7 projects. It has been developed in the framework of the Spanish Virtual Observatory project supported by the Spanish MINECO through grant AYA 2011-14052 and the CoSADIE FP7 project (Call INFRA-2012-3.3 Research Infrastructures, project 312559).
The system is maintained by the Data Archive Unit of the Centro de Astrobiología (CAB, INTA-CSIC).
