Properties of different large fields mapped by Herschel.
|Field||Mode||N(rep)||Time||Area||Noise level in mJy|
|[hr]||[deg2]||5σ at 250 μm|
Notes. Columns (1) name of the field observed by Herschel; (2) Herschel observing mode; (3) total number of repeats of the observing mode in the set; (4) total time of observations; (5) field area of good pixels; (6) total noise from the literature. Noise is calculated using the relation . The bottom six fields are areas with different design levels nested as a part of HerMES: total area covered in HerMES is 380 deg2. Shallow HeLMS field covers the area of 274 deg2, and deeper Level 1–Level 6 fields cover the total area of about 80 deg2. FLS and Lockman-SWIRE have been used to probe 500 μm-risers selection by Dowell et al. (2014), while Asboth et al. (2016) applied the same selection method in the HeLMS field.
