Updated to 2.7.1. ZCB PSP FIELDS Merged Search Coil Magnetometer and Fluxgate Magnetometer (SCaM), SCaM data. 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.

This is a bitwise variable, meaning that multiple flags can be set for a single time, by adding flag values. Current flagged values are: 1: FIELDS antenna bias sweep, 2: PSP thruster firing, 4: SCM Calibration, 8: PSP rotations for MAG calibration (MAG rolls), 16: FIELDS MAG calibration sequence, 32: SWEAP SPC in electron mode, 64: PSP Solar limb sensor (SLS) test. 128: PSP spacecraft is off umbra pointing. 256: High frequency noise affecting RFS and TDS receivers. 512: Antennas driven towards the FIELDS power supply rails. A value of zero corresponds to no set flags. Not all flags are relevant to all FIELDS data products, refer to notes in the CDF metadata and on the FIELDS SOC website for information on how the various flags impact FIELDS data. For more information on the quality flags describing high frequency noise and antennas driven to the rails, see release notes for PSP/FIELDS releases 8 and 9.
