    157 == SDQA Alerts == 
    158   
    159 Most faults listed above could impact SDQA operations temporarily at some level. A few would permanently impact the recorded quality, e.g. the bullet on "bad images" in the subsection on software faults. The list below includes faults with data that are *not* caused by any of the faults listed above. SDQA is basically characterization of faultiness of actual data, in the range "useless" to "perfect". Fault-like alerts will be generated by: 
    160  
    161   * one or more image metrics outside acceptable threshold (e.g. delivered seeing inferior to minimum goal) 
    162   * image artifacts beyond preset tolerance (e.g. anomalously high rate of cosmic rays, meteor trails) 
    163   * images partially or totally impacted by cloud cover
