Comparative h‐ and m‐indices for Fifteen Ground‐ and Space‐Based Observatories

The following graphics and chart are based on the STScI report "Comparative h‐ and m‐indices for Fifteen Ground‐ and Space‐Based Observatories" in this pdf file:   h-andm-indexComparisonThru2016v1.2.pdf. Please read the report to understand the methodology used when calculating values found in the plots and table below.

Please note: The SOFIA data in this report represents the starting point at first light, Nov 30, 2010. The SOFIA program declared full operations on May 29, 2014. Indices for this relatively young observatory should be measured at a later date for a fuller and more accurate picture of productivity. As a unique airborne observatory, future assessments should measure SOFIA against other observatories while taking into account the available hours for data collection for this unique non-space, non-ground observatory.
