IMAGES for Wet Deposition (https://www3.epa.gov/castnet/prismdep.html)

are located on: https://newftp.epa.gov/webclient/WebClient.xhtml
in folder: CASTNET/tdep/2022_01_images

Species: so4_ww, n_ww, no3_ww, nh4_ww, precip_ww, ca_ww, mg_ww

**note: we decided to utilize tdep images for these species as the DRY and TOTAL deposition products are in kg element per hectaire (i.e. KG S ha-1 from SO4) 
rather than the KG SO4 ha-1 that the old maps utilized. This makes the wet deposition consistent with the DRY and Total deposition.

IMAGES for Precipitation Chemistry (https://www3.epa.gov/castnet/precipchem.html)

These should be dropped as these are not a CASTNET product. 

Also a revision in the main code for legend handling is needed for species with maximum values > 1, if this decision is to be revisited.
