For an example of how to make a reference stack see [wiki:md06.refstack.y ]

The tessellation that exposures are warped to is set by ippconfig/recipes/nightly_science-config

survey	tess_id
M31	M31
MD01	MD01.V2
MD02	MD02.V2
MD03	MD03.V2
MD04	MD04.V2
MD05	MD05.V2
MD06	MD06
MD07	MD07
MD08	MD08.V2
MD09	MD09.V2
MD10	MD10.V2
MD11	MD11.V2
STS	STS

• The label of the reference stacks used for nightly science are set by the stdscience input file

• Currently, MD06 is missing y and STS is only in r.

• We have STS.V2, why is that not used for nightly science

• We need MD06 and MD07 in V2, and probably M31 in the other bands (for V2)

• We do not have a refstack for MD11?
