Summary of the main input records used by PhotPipe for Gaia DR2.

Type	No. records
G–band FoV transit	51,712,381,972
BP/RP raw FoV transit	51,715,475,265
Spurious detections	10,737,486,581
IDU cross-match sources	2,582,614,429
AGIS sources	2,499,375,298

Notes. The spurious detections are a subset of input G–band transits and have been excluded from the cross-match because they may be associated with artefacts from bright sources. AGIS sources refer to the number of source records with sky positions determined by AGIS.
