Results are provided for logT in the range of 3.0-7.4 in steps of 0.1. The level indices refer to the ordering given in Table 2 text where the energies are also given. The format is most easily described by the fortran program provided - readups.f - which may be used to interface with user programs. Oscillator strengths for all dipole allowed transitions are provided in osc.dat which are also indexed with respect to Table 2.</description><source format="bibcode">2000A&amp;AS..143..483B</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/143/483</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/103/273">J/A+AS/103/273 : IRON Project II IR collision strengths of C-like ions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/283/319">J/A+A/283/319 : IRON Project III B-like ions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/108/1">J/A+AS/108/1 : IRON Project V Collision strengths of O-like ions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/293/953">J/A+A/293/953 : IRON Project VI Fe II collision strengths</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/293/967">J/A+A/293/967 : IRON Project VII Fe II radiative transitions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/109/193">J/A+AS/109/193 : IRON Project VIII Electron excitation of Ti-like ions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/119/509">J/A+AS/119/509 : IRON Project XVII Radiative transition in Fe III</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/119/523">J/A+AS/119/523 : IRON Project XVIII Electron impact for Fe III</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/120/361">J/A+AS/120/361 : IRON Project XIX Fe II radiative transitions</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/123/159">J/A+AS/123/159 : IRON Project XXII C and O radiative rates</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/123/575">J/A+AS/123/575 : IRON Project XXIII Fe XXII excitation rate coefficients</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/126/373">J/A+AS/126/373 : IRON Project XXVII Fe IV collision strengths</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/131/499">J/A+AS/131/499 : IRON Project XXIX Boron isoelectronic sequence</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/131/153">J/A+AS/131/153 : IRON Project XXXI Fe XII electron excitation</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/135/347">J/A+AS/135/347 : IRON Project XXXV Fe XXIV &amp;
