Hubble Space Telescope WFC3 filenames

WFC3 filenames

Note: The WFC3 files names are all starting with the letter 'I'

Note: The 9th character of an association of simple observation is always '0' at CADC

Note: Please consult the full documentation Here

The suffixes used for WFC3 raw and calibrated data products are described in the following and closely mimic those used by ACS and NICMOS.
