# Plot The Masked Data
# ~~~~~~~~~~~~~~~~~~~~~
# Now apply the mask and plot the masked data. The mask applies to every band in your data.
# The mask values below are values documented in the Landsat 8 documentation that represent
# clouds and cloud shadows.

# Generate array of all possible cloud / shadow values
cloud_shadow = [328, 392, 840, 904, 1350]
cloud = [352, 368, 416, 432, 480, 864, 880, 928, 944, 992]
high_confidence_cloud = [480, 992]

# Mask the data
all_masked_values = cloud_shadow + cloud + high_confidence_cloud
arr_ma = em.mask_pixels(arr_st, landsat_qa, vals=all_masked_values)

# sphinx_gallery_thumbnail_number = 5
ep.plot_rgb(
    arr_ma, rgb=[4, 3, 2], title="Array with Clouds and Shadows Masked"
)
plt.show()
