Resource Description:
For a list of all services and tables belonging to this table's resource, see Information on resource 'Coordinated microlensing survey observations with Kepler K2/C9 using VST'
This table has an associated publication. If you use data from it, it may be appropriate to reference http://archive.eso.org/wdb/wdb/eso/sched_rep_arc/query?progid=097.C-0261(A) either in addition to or instead of the service reference.
To cite the table as such, we suggest the following BibTeX entry:

VO nerds may sometimes need VOResource XML for this table.
These are the coefficients of the transformation polynoms of the reference frame to the transformed reference frame (for which the kernel is computed). The transformation equations are:
xct = c[0]*xc + c[1]*yc + dx yct = c[2]*xc + c[3]*yc + dy
where c is given in corr_coeff, dx and dy are from the columns,
