-Reading Offline hits
-====================
-
-The following example shows how to access hits data in an offline ROOT file, which is
-written by aanet software.
-
-Note: the offline file used here has MC offline data and was intentionaly reduced
-to 10 events.
-"""
-import km3io as ki
-from km3net_testdata import data_path
-
-#####################################################
-# To access offline hits/mc_hits data:
-
-mc_hits = ki.OfflineReader(data_path("offline/numucc.root")).events.mc_hits
-hits = ki.OfflineReader(data_path("offline/km3net_offline.root")).events.hits
-
-
-#####################################################
-# Note that not all data is loaded in memory, so printing
-# hits will only return how many elements (events) were found in
-# the hits branch of the file.
-
-print(hits)
-
-#####################################################
-# same for mc hits
-
-print(mc_hits)
-
-#####################################################
-# Accessing the hits/mc_hits keys
-# -------------------------------
-# to explore the hits keys:
-
-keys = hits.keys()
-print(keys)
-
-#####################################################
-# to explore the mc_hits keys:
-
-mc_keys = mc_hits.keys()
-print(mc_keys)
-
-#####################################################
-# Accessing hits data
-# -------------------------
-# to access data in dom_id:
-
-dom_ids = hits.dom_id
-print(dom_ids)
-
-#####################################################
-# to access the channel ids:
-
-channel_ids = hits.channel_id
-print(channel_ids)
-
-#####################################################
-# That's it! you can access any key of your interest in the hits
-# keys in the exact same way.
-
-#####################################################
-# Accessing the mc_hits data
-# --------------------------
-# similarly, you can access mc_hits data in any key of interest by
-# following the same procedure as for hits:
-
-mc_pmt_ids = mc_hits.pmt_id
-print(mc_pmt_ids)
-
-
-#####################################################
-# to access the mc_hits time:
-mc_t = mc_hits.t
-print(mc_t)
-
-#####################################################
-# item selection in hits data
-# ---------------------------
-# hits data can be selected as you would select an item from a numpy array.
-# for example, to select DOM ids in the hits corresponding to the first event:
-
-print(hits[0].dom_id)
-
-#####################################################
-# or:
-
-print(hits.dom_id[0])
-
-#####################################################
-# slicing of hits
-# ---------------
-# to select a slice of hits data:
-
-print(hits[0:3].channel_id)
-
-#####################################################
-# or:
-
-print(hits.channel_id[0:3])
-
-#####################################################
-# you can apply masks to hits data as you would do with numpy arrays:
-
-mask = hits.channel_id > 10
-
-print(hits.channel_id[mask])
-
-#####################################################
-# or:
-
-print(hits.dom_id[mask])
