1.47. doHrsFreq

Full Name: herschel.hifi.pipeline.hrs.DoHrsFreqTask
Alias: doHrsFreq
Type: Java Task - Java Task
Import: from herschel.hifi.pipeline.hrs import DoHrsFreqTask

HIFI/Pipeline/HRS Pipeline


Step11: Task which computes the frequency of the HRS sub-bands.

The parameter "model" of this Task permits to choose between:

  • "model" ==> creation of the HRS frequency Linear Model.

  • "column" ==> creation of the frequency columns.

If the model is Chosen, the parameters of the model are the LOs values and the sampler name for every sub-band. Those parameters can change from scan to scan.

If the columns are chosen, this task will create columns named "frequency_1", "frequency_2", etc.


Example 1: In HIPE
from herschel.hifi.pipeline.hrs import *
htp = HifiTimelineProduct(df, hk)
doHrsQDCFull(htp=htp, cal=calHrsQDCFull)
doHrsPowCorr(htp=htp, cal=calHrsPowCorr)
doHrsWindow(htp=htp, window="hanning")
doHrsSymm(htp=htp, zeros="multiple")
doHrsFFT(htp=htp, algo="DFT")
doHrsSmooth(htp=htp, smooth="none")
doHrsFreq(htp=htp, model="column")

API details


HifiTimelineProduct htp [INOUT, MANDATORY, default=No default value]

The HifiTimelineProduct which contains the HRS spectra.

String model [INPUT, OPTIONAL, default="column"]

The indicator to select between frequency columns ("column") or frequency model ("model").
