We have updated the [ https://hub.iris.washington.edu/zimbra/service.iris.edu/mustang/noise-psd/1/ | noise-psd ] web service to change the y-axis label when plotting PSD values that do not have their instrument response removed (also known as uncorrected PSDs). This label previously read as "Power[10log10(m**2/Hz)][dB]", which has the appropriate units for PSD values that do have their instrument response removed (corrected PSDs). The label now reads as ''Power[10log10(counts**2/Hz)][dB]", which are the proper units for uncorrected PSDs. These plots are requested using the service parameter "&correct=false".
PSD plots made using the "&correct=true" parameter, which is the default, still retain the y-axis label "Power[10log10(m**2/Hz)][dB]".
