Notes.

^(a)

Observing date in format year, month, day.

^(b)

Starting time (UT) of observations in format hour, min, s.

^(c)

The OBSID number encodes the IRIS observing configuration in a unique number (see Tables 12–14 in De Pontieu et al. 2014a). The combination ⟨Date⟩_⟨Time⟩_⟨OBSID⟩ constitutes a unique identifier to the dataset.

^(d)

The IRIS spectrograph slit covers a region on the Sun through a raster of n slit positions, with a separation of type: dense (035), sparse (1″), or coarse (2″). Raster type s&s is the “sit-and-stare” mode for which the slit remains fixed at one location. The area covered is shown in the FOV column, and the temporal cadence in the Cad. column.

^(e)

Target: AR: active region, QS: quiet Sun, CH: coronal hole, S: sunspot.

^(f)

Pointing coordinates at the beginning of the time series, the target is followed by tracking solar rotation.

^(g)

μ = cos θ with θ the observing angle.

^(h)

Duration of overlap of SST observations with IRIS in format hh:mm:ss.

⁽ⁱ⁾

Spectral lines observed with SST. CRISP is operated independently from the instruments on the blue beam; with fixed interference filters (Ca II H) or CHROMIS (Ca II K). The instruments have their own cadences and overlap times and are separated in rows in the table.

^(j)

Cadence of the SST observations.

^(k)
