Paper counts

This table shows the refereed-paper counts per telescope and year.

Number of refereed papers per year [ PNG ].

Number of refereed papers since first-light year [ PNG ].

Number of refereed papers per year [ PNG ].

Cumulative number of refereed published papers per year and telescope [ PNG ].

Service, Override and Archival papers

Publications that make use of data obtained as part of the ING Service Programme, the ING Override Programme or from the ING Archive.

Left: Relative distribution of WHT refereed papers since first light and origin of the data (private instrument, archive, service or override). Right: same for the INT, including some surveys [ PNG | PNG ].

Papers in Nature and Science journals

A compilation of Nature and Science papers is available.

Cumulative number of papers (partly) based on ING data published in journals Nature or Science. If a paper makes use of data from more than one ING telescope, then it's counted once [ PNG ].

Paper citations

These tables show the refereed-paper citations per telescope and year.

Citations per year. The dashed lines show median values of citations per year from the years of stable paper production and citations: 6144 citations/year (WHT, 1998-2014), 4228 citations/year (INT, 1995-2014), and 1484 citations/year (JKT, 1995-2004). The jump in 1999 is produced by the paper Perlmutter et al., 1999, ApJ, 517, 565 (12870 citations).


Yearly median citations per paper when papers per year are greater than or equal to 10. The dashed lines show the median values from the years of stable paper and citation production: 37 cit/paper (WHT, 1998-2014), 36 cit/paper (INT, 1995-2014), and 31 cit/paper (JKT, 1995-2004).


Yearly variation of the h index. The dashed lines show average values from the years of stable paper production and citations: 42 (WHT, 1998-2014), 34 (INT, 1995-2014), and 21 (JKT, 1995-2004).

Top most cited papers

The top 25 most cited papers from every ING telescope are listed in the Top most cited papers web page.

Telescope performance

Time on sky:

Relative-to-night-length on-sky time defined as 100%-(weather downtime percentage)-(technical downtime percentage)-(standdown percentage) excluding from the calculation S/D/commissioning nights as well as nights when visiting instruments were used [ PNG ].

Technical downtime:

Percentage of technical downtime per semester excluding from the calculation S/D/commissioning nights as well as nights when visiting instruments were used [ PNG ].

Weather downtime:

Relative-to-night-length percentage weather downtime per year (semesters A+B) excluding from the calculation S/D/commissioning nights as well as nights when visiting instruments were used. Blue: WHT, yellow: INT. The dotted lines show the average values (WHT average: 23.1%, INT average: 23.4%) [ PNG ].

Relative-to-night-length percentage weather downtime per semester excluding from the calculation S/D/commissioning nights as well as nights when visiting instruments were used. [ PNG ].

Telescope time allocation and paper authorship

Number of allocated nights per type of allocation (time allocation committee, observing scheme, organisation, project) [ PNG ].
Number of allocated nights per type of allocation (time allocation committee, observing scheme, organisation, project) [ PNG ].

Nationality of first author's first affiliation in refereed papers that used data from the ING telescopes since 1984. [ PNG ].

Instrument time allocation and paper use

Allocated nights per instrument on the WHT. Only science nights are considered. Every year comprises data from semesters A and B. INGRID refers to when it was used without adaptive optics. NAOMI includes INGRID, OASIS and OSCA in combination with adaptive optics [ PNG ].

Instrument use in WHT refereed papers since first light [ PNG ].

Allocated nights per instrument on the INT. Only science nights are considered. Service nights are excluded. Every year comprises data from semesters A and B [ PNG ].

Instrument use in INT refereed papers since first light [ PNG ].

Journal publication

Paper distribution in the scanned refereed journals (since 1984) [ PNG ].

User feedback

WHT and INT user overall satisfaction rating as recorded in the observer feedbacks when they leave, since 1999 [ PNG ].

Comparison with other telescopes

Count checks

Paper counts by ING (blue) and retrieved from ADSLabs (red, http://labs.adsabs.harvard.edu/fulltext/) as a result of scanning the refereed journals listed below, and searching for a list of specific keywords: "William Herschel Telescope" OR "William Herschel Telescopes" OR "WHT". While the ING counts only include papers that make a direct use of the data, the ADS counts include all the papers that contain the searched keywords. The dashed line shows the ADS paper count but including all the refereed journals in the ADS database [ PNG | TIFF ].

While the ING counts only include papers that make a direct use of the data, the ADS counts include all the papers that contain the searched keywords.
