Here, we briefly summarize the data reduction steps we adopted. Complete accounts of reduction processes will be presented in the forthcoming papers of the series (D.Ladjal et al.  [*in prep*]{}; K. M. Exter et al. [*in prep*]{}). A summary of the HerPlaNS data products and their characteristics is given in Table\[datasummary\].

### Broadband Imaging

To generate broadband images, we used the Herschel interactive processing environment (HIPE, version 11; @hipe) and Scanamorphos data reduction tool (Scanamorphos, version 21; @scana). First, the raw scan map data were processed with HIPE from level 0 to level 1. During this stage, basic pipeline reduction steps were applied while the data were corrected for instrumental effects. The level 1 data were then ingested into Scanamorphos, which corrects for brightness drifts and signal jumps caused by electronic instabilities and performs deglitching, flux calibration, and map projection. Scanamorphos was chosen as our map-making engine over
