| Abstract: |
Multi-wavelength analysis of archival data can lead to groundbreaking
discoveries. Following our ADASS tutorial in 2015, we discovered a population of
intermediate-mass black holes using archival data from SDSS, Chandra, and XMM-Newton, which became a major contribution to the field. Despite the final success,
our team faced numerous quite serious issues with data formats, access, reduction and
analysis tools which slowed down the project by about 1.5 years. Here we outline the
most important challenges we faced and discuss the workarounds and a path forward.
Presently, to succeed in multi-wavelength archival research, one really needs to be an
expert in observations and data reduction in every spectral domain being used. The main
obstacle is that some major space missions and most ground-based observatories do not
provide science ready data in the archives or provide them only for a small fraction of all
observations. Data reduction efforts require very high time and manpower investments.
Even when reduced data are available, they often do not conform to any standards (from
FITS WCS representation to IVOA standards for metadata). A potential path forward is
to organize a push from the funding agencies towards data providers to deliver science
ready data which would comply to the FAIR principles. |
