Observation of Crab at different off-set angles was essential to characterise the IBIS large FOV response to weak sources. This is particularly relevant for low energy (E<40 keV) affected by mask transparency.

Programmatics 1/2

L’IASF ha partecipato alla realizzazione di parti di tutti gli strumenti di bordo e ha contribuito allo Integral Scientific Data Centre (ISDC)

IBIS (PI IASF), progettato e realizzato da un consorzio internazionale di 14 Istituti di 9 nazioni diverse con contributo principale Italo-Francese sotto la guida della

ditta Laben (prime contractor ed assembly company)

Contributi importanti all’hardware di volo per SPI e Jem-X

Spacecraft realizzato dall’Alenia Spazio, prime contractor, con contratto ESA

Fondamentale partecipazione allo ISDC

Il contributo Italiano e’ stato quindi essenziale al successo di questa missione.



Programmatics 2/2

Tutti i gruppi di lavoro delle differenti sezioni (Roma, Palermo, Bologna, Milano e Ferrara) sono attualmente coinvolti nelle operazioni in volo relative alla ottimizzazione del funzionamento dei rivelatori di bordo e alle fasi di calibrazione previste ogni 6 mesi.

Partecipano inoltre alle attivita’ di controllo della missione dal punto di vista scientifico presso il centro operativo ESOC/ESA e all’ISDC.

Ad un anno dalla immissione in orbita l’Osservatorio funzione in modo nominale, sta’ fornendo dati scientifici di altissima qualita’ alla comunita’ scientifica interazionale oltre 100 lavori sono pubblicati o in via di pubblicazione su ApJ, A&A Letters-special issue, Nature etc.

Riprova dell’interesse scientifico della comunita’ e’ l’over subscription del programma scientifico di AO2, pari a un fattore 9 (anni di osservazioni richieste per il 2004).

The Integral Mission ExtensionAt its 105th meeting held on 5-6 November 2003 the ESA’s Science Programme Committee (SPC) unanimously approved a 4-year “rolling” extension to Integral operations from

17 December 2004 until 16 December 2008

The Astronomy Working Group (AWG) and Space Science Advisory Committee had earlier expressed their general satisfaction with the current status of the mission, its initial science return and promise for the future. This “rolling” extension means that towards the end of the first two years the level of resources required for the third and fourth years will be reviewed by the SPC. Should the scientific return remain high and the technical status appropriate then at the same time the SPC would be asked to approve a further 2 years of Integral operations. Thus, a 4-year horizon would be established at each approval cycle. The planning for this 4-year extension maintains the current scientific capability of the mission. In any future mission extensions it may be appropriate to reduce the level of operational support, so decreasing costs, but at the expense of scientific capability.

The SPC also made two other decisions concerning Integral. They confirmed that the amount of observing time available to the astronomical community during the first three years of the extension will be 75%, with the remaining 25% being for the Integral Science Working Team (ISWT). The ISWT is composed of the instrument and data centre principal investigators, mission scientists, the project scientist, and representatives of the US and Russian scientific communities. During these 3 years, ESA will continue to issue Announcement of Opportunities for observing time, the 1-year proprietary data period will remain, and the Russian scientists will continue to be guaranteed their share of observing time. Data rights for extension years 4 and beyond will be discussed by those involved before a proposal is presented to the SPC. During the extension ESA proposes to establish an Integral User’s Group in order to benefit from the best possible advice from a wide community of interested users.



Core Programme (guaranteed time)

35% (year 1), 30% (year 2), 25% (year 2+) of the total observing time is reserved for institutes which have developed and delivered instruments and the data centre (guaranteed PI time), for Russia and NASA for their contributions to the programme, and - to a smaller extent - for Mission Scientists and ISOC.

The Core Programme, consists of three elements:

-Deep exposure of the central Galactic radian, centred on (l, b) = (0, 0). Individual pointings (30 min exposure each) on a set of regular pointing grids. -the Survey of the Galactic plane to map its gamma-ray emission, to detect as yet

unknown persistent sources (e.g. recent Galactic supernovae) and to facilitate the study of transient sources.

This survey is made out of 1 scan per 12 days or 4 revolutions ("slew, stop, stare") along a saw-tooth path (inclined at 21 deg wrt gal equator).

Each scan consists of a series of individual exposures (2200 sec each) separated by 6.0 deg along the scan path. Individual scans are shifted by 27.5 deg in galactic longitude. The scan pointings cover a band of +/- 6.5 deg in galactic latitude, the actual coverage is larger (i.e. apx +/- 20 deg), however, due to the wide FOV's of the instruments.

P.Ubertini is member of the ISWT with main task of:• maximize the scientific return of INTEGRAL within the technical and programmatic boundary

conditions • ensure that INTEGRAL maintains its principal characteristics as an observatory satisfying the

objectives of the scientific community at large • act as a focus for the interest of the scientific community in INTEGRAL • maintain contact with the wider astronomical community on matters specific to INTEGRAL so

that it can advise ESA on INTEGRAL's scientific goals from a general point of view • These tasks will be achieved by: • reviewing, in the light of recent results, the scientific goals of INTEGRAL at regular intervals

while considering the technical boundary conditions of the spacecraft • advising on the scientific aspects of the development of the INTEGRAL instrumentation • establishing the core observing programme based on the scientific objectives of INTEGRAL • identifying areas of overlap, complementarity, redundancy and omission between instruments

both in function and in operation and optimizing the scientific use of the instruments • identifying and implementing a simple operational approach • identifying a coherent calibration and performance verification policy both on the ground and

also in orbit • participating in the major project reviews • performing specific tasks as needed during the project's development • Concerning the science ground segment, the ISWT will be responsible to: • optimise the core observing programme from an operational point of view • advise on the development of the science ground segment of the observatory including the

ISDC with particular reference to the operational scenario, software, observatory products and the INTEGRAL database structure

• monitor and actively support the ISDC activities during operation to ensure they correspond to the needs of the scientific users community.
