Notes. The columns list the frame identification, instrument/detector mode, the used filters in the filter wheels FW0, FW1, and FW2, detector integration times (DIT), number of integrations (nDIT) per exposure, the number of exposures (nEXP), and the estimated dark current (dc) level in ct per pix and frame (or per DIT).

(a)

The file identification corresponds to the fits-file header keyword “origname” without prefix “SPHERE_ZIMPOL_”. The first three digits give the day of the year followed by the four-digit observation number.
