Sample Queries

Plot
../query?target=IU.ANMO.00.BHZ.M

Make frequency the horizontal axis instead of time:
../query?target=IU.ANMO.00.BHZ.M&plot.horzaxis=freq

Output Differenced to Peterson Low Noise Model:
../query?target=IU.ANMO.00.BHZ.M&output=dlnm

Output Differenced to Median Values of Daily Modes:
../query?target=IU.ANMO.00.BHZ.M&output=powerdmedian

Fixed Color Scale -170 to -110 [dB]:
../query?target=IU.ANMO.00.BHZ.M&plot.powerscale.range=-170,-110

Use Colors Accessible to Colorblind Users:
../query?target=IU.ANMO.00.BHZ.M&plot.color.palette=RdYlBu

Create A Plot That Can Be Printed in Grayscale (and Photocopied):
../query?target=IU.ANMO.00.BHZ.M&plot.color.palette=OrRd
