Notes.

(a)

For comparison purposes, cross-calibration of the iM and i2M catalogs was used to provide a pseudo-measurement of BD +17 4708 in i2M (see Sect. 5.3)

(b)

Errors quoted from the systematic error budget (cf. Table 5).

(c)

Estimate of the uncertainty affecting the combination of solar analog measurements. The model includes the (potentially correlated) contributions from measurement noise, zero point determination uncertainty, flat-field noise, atmospheric variation, airmass correction, survey uniformity and aperture correction uncertainty.

(d)

Difference between the two determinations of the offset.
