Problem with situationmask = 32

[tjsnh]

Trying to make a science experiment that can only be performed "in space high above". This would seem to be situationmask 32, but it's not working. When I use a mask of 63 I can perform the experiment anywhere, so I'm pretty confident the part is working correctly. Any insight to what I might have missed? Here is my code:

From ScienceDefs.cfg :
 

EXPERIMENT_DEFINITION
{
    id = highresimage
    title = High Resolution Image
    baseValue = 5
    scienceCap = 10
    dataScale = 1
    requireAtmosphere = False
    situationMask = 32
    biomeMask = 3
    
    RESULTS
    {
        default = You record a high-res image.

    }

}

 

From part.cfg

 

  MODULE
    {
        name = ModuleScienceExperiment
        experimentID = highresimage
        experimentActionName = Take High-Res Picture
        resetActionName = Delete Data
        useStaging = False
        useActionGroups = True
        hideUIwhenUnavailable = True
        xmitDataScalar = 1
        dataIsCollectable = True
        collectActionName = Take Data
        interactionRange = 2
        rerunnable = True
        resettableOnEVA = True
//        FxModules = 0
//        usageReqMaskInternal = 1
//        usageReqMaskExternal = 8
    }
