I have a Geoserver imagemosaic layer serving out a timeseries of 2band rasters with band names GRAY_BAND and Band2. When I query the layer
both bands are returned I believe the map only shows Band2, but if I click on a point in geoservers openlayers previewer it shows values for both bands. Is there a way specify via a param which band is returned? My goal is to get the single band so I can apply an SLD color ramp to it.
I did see that you can use propertyName=GREY_BAND, which specifies the band in the GetFeatureInfo response, but even when specifying propertyName it seems like the SLD is applied to a composite of both bands.
