Pass Requirements
Define what it is to passis a first-order measure of data integrity assessed upon receipt. Once received, ‘Data Packets’ are inspected and their contents examined to substantiate content (reasonable file sizes) and verify file formats. Expected file formats for either L0, L2 or L3 products should be consistent with Multibeam Guidelines (section 2.3.1.2 Table 5). This data is saved and archived as a directory index of data received.
Checks
The directory structure and contents of data packets are scanned, tallied and listed upon reception to provide first-order verification and identify anomalies.
Listed files are checked against expected/recommended Multibeam Guidelines (section 2.3.1.2 Table 5) for their respective process level (either L0, L2 or L3). File sizes are assessed by the user for legitimacy (e.g. > 0 kb)
Listed files are archived as a text file with the date of data reception recorded.
Pass Requirements
Files are of the appropriate format (e.g. HDCS compatible extensions) and are sufficiently substantial (e.g. > 0 kb).
