This survey provides for the first time an unbiased census of outflows over a significant portion of a giant molecular cloud, and yields a sample of outflows free from selection effects and with all objects located at roughly the same, well-known distance. In this paper, we present the data gathered in the course of the survey, provide a comprehensive list of all molecular hydrogen emission features found, and give a list of the 76 candidate outflows identified in the data set.

Note (1): Representative coordinate for the jet, as follows. If there is a candidate driving source, its position is given; alternatively, if the location of a possible driving source is suggested on morphological grounds, e.g., the geometric centre of a apparently bipolar H2 configuration, this position is given. Failing this, the position of a prominent part of the candidate H2 flow is given. Note (2): A distance to the Orion A cloud of 450pc is assumed. Note (3): Luminosity of all H2 features associated with the flow; no corrections for the unknown extinctions were applied. The total H2 luminosity LH2, which accounts for emission in other H2 lines, may be roughly calculated by multiplying L2.12 by 10. Note (4): Blank if the flow lies outside the CS(1-0) survey area or too close to its edge Note (5): ON: flows which are not included in the analysis to be presented in subsequent papers because they lie too close to the Orion Nebula. -: flows apparently not associated with a CS(1-0) core

Note (1): In many cases, this note also mentions the suspected driving source, as identified in either published data or publicly available data (e.g., IRAS data), or as seen in our own data. However, the identification of the driving sources and their further characterisation remains incomplete, and a more detailed and complete discussion of the jet driving sources is deferred to a future paper. The acronym CRW denotes the millimetre continuum sources found in OMC-2/3 by Chini et al. (1997ApJ...474L.135C), while "RN" stands for "reflection nebulosity".
