Merged SCaM data is composed of SCM and MAG data from the FIELDS experiment on the Parker Solar Probe spacecraft [1]. For a full description of the FIELDS experiment, see [2]. The SCM is sampled by the Digital Fields Board (DFB), discussed in ref. [3]. For an overview of FIELDS/MAG calibration see ref. [4].SCaM data consists of continuous time-series data from the SCM and MAG sensors. Merged SCaM data is a Level 3 (l3) product derived from the direct sum of weighted and time corrected l1 MAG and SCM data [4]. The weighting coefficients are designed to optimize the SCaM signal to the integrated instrumental noise floor.The Level 3 SCaM product uses SCM data which has been calibrated for (i) DFB in-band gain, (ii) DFB analog filter gain/phase response, (iii) DFB digital filter gain/phase response, and (iv) the SCM preamplifier gain/phase response. The SCM data is empirically gain-matched to the MAG, with correction factors included in the metadata [4]. Information on SCM sample rate is provided at a 1 min cadence.The Level 3 SCaM product uses orthogonalized MAG data with spacecraft zero offsets removed. Spacecraft zero offset data, along with the native MAG range and sample-rate meta-data is provided at a 1 minute cadence. The Level 3 SCaM data product in this file may be in spacecraft coordinates (e.g. X,Y,Z), RTN coordinates (R,T,N), or SCM sensor coordinates (U,V,W). For large parts of the PSP mission, anomalous performance of the SCM sensor-X axis (in the U direction) precludes merging in SC or RTN coordinates. In these cases data is only provided for the SCM sensor coordinate system (V,W).References: 1. Fox, N.J., Velli, M.C., Bale, S.D. et al.
