Use of observing time and scientific productivity

ING Annual Report's chapter on the use of observing time and scientific productivity:

WHT only data:

Posters:

Telescope performance

Time observed:

Relative-to-night-length observed time defined as 100-(weather downtime percentage)-(technical downtime percentage) [ PNG ].

Technical downtime:

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

Fraction of observing time lost to bad weather at the WHT (blue curve) and INT (yellow). [ PNG ]

Fraction of observing time lost to bad weather at the WHT, 1989 to present. The average downtime is ~20% in semester A (February to July) and ~28% in semester B (August to January) [ PNG ]

Monthly variation of usable observing time and length of night from 1989 to present. The thick black line represents the duration of astronomical night in hours. The border of the pink area shows the (rather small) monthly variation in the number of hours of good weather available, from a minimum in April, to a maximum in September. [ PNG ]

Monthly variation of % of nights with some weather downtime from 2002 to present. The dashed line shows the % of time lost to bad weather on the WHT (i.e. same as two figures above). [ PNG ]

Telescope time allocation and paper authorship

WHT nights per type of allocation:

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

INT nights per type of allocation:

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

Paper authorship and nationality:

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

Instrument time allocation and paper use

WHT nights per instrument:

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

INT nights per instrument:

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 ].

Journal publication

WHT and INT paper distribution in the refereed journals scanned from 2011 to present time. [ PNG ].

User feedback

WHT and INT user satisfaction rating, as recorded in the observer feedbacks when they leave, from 1999 to present time. [ PNG ].

Comparison with other telescopes

  • Scientific impact of large telescopes 1991-1998.
    Number of Nature papers generated 1989-98 by ground-based optical telescopes with mirror diameter >3.5m (for comparison, figures for the 2.5-m INT and Nordic Optical Telescope are also included) [ JPEG | TIFF ].

  • The WHT one of the most scientifically productive telescopes in the world: C Benn and S Sánchez, 2001, "Scientific Impact of Large Telescopes", ING Newsl, 4, 15.
  • Comparison of ESO telescopes with other observatories, including ING:

    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 ].

    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: "Isaac Newton Telescope" OR "Isaac Newton Telescopes" OR "INT telescope". 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 ].

    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: "Jacobus Kapteyn Telescope" OR "Jacobus Kapteyn Telescopes" OR "JKT". 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 ].

    Refereed journals scanned: Astronomy and Astrophysics, Astronomical Journal, Astrophysical Journal (including Letters and Supplement Series), Monthly Notices of the Royal Astronomical Society, Nature, Publications of the Astronomical Society of the Pacific and Science.
