2022 March 19: The HLA footprint viewer no longer works
because it relies on Flash. If you need footprints, we
recommend using the
MAST Portal.
Note that the Portal also gives access to the new
Hubble Advanced Products (HAP), which include more recent
observations.
The HLA contains no observations acquired after
2017 October 1.
The original
ST-ECF DER_SNR
page can be accessed via this link.
This page contains the implementation of a signal-to-noise ratio estimator, DER_SNR, that follows
the definition set forth by the Spectral Container Working Group of ST-ECF, MAST and CADC.
A detailed description and discussion of the algorithm can be found in
Issue #42 of the ST-ECF newsletter.
The following code is maintained by Felix Stoehr <fstoehr [at] eso [dot] org>.
