lib_pcal module¶
Phase calibration routines.
-
lib_pcal.
accumulate_pcal
(acc_pcal, v1pcal, count_acc_pcal)[source]¶ [Used in one-baseline-per-task mode.]
-
lib_pcal.
accumulate_pcal_all
(acc_pcal, pre_pcal, n_bins_pcal, dtype_complex=<class 'complex'>)[source]¶ Accumulate pcal window (all-baselines-per-task mode).
-
lib_pcal.
adjust_shift_acc_pcal
(acc_pcal, F_pcal_fix, bypass_adjust_pcal=0, v=0)[source]¶ Remove delay shift due to delay model.
- acc_pcal
- accumulation matrix for the phase calibration signals.
- F_pcal_fix
- number of samples to roll each of the arrays in acc_pcal.
- bypass_adjust_pcal
- 0 by default.
- v
- verbose if 1.
- acc_pcal_out
- acc_pcal with the rolls (circular shift) applied as defined in F_pcal_fix.
TO DO:Asses error raised from this correction. It should be inside a sample in phase.Check that corrections are applied to the proper row (F_refs...).
-
lib_pcal.
get_pcal_ind
(freqs, sidebands, fs, f_pcal, o_pcal)[source]¶ Compute window length for phase calibration and get tone seperation.
- freqs : list of float
- start frequency for the bands [Hz].
- sidebands : list of str
- sideband identifier (L/U).
- fs : int
- sampling frequency [Hz].
- f_pcal : int
- frequency separation for phase calibration tones [Hz].
- o_pcal : int
- frequency offset for phase calibration tones [Hz].
- n_bins_pcal
- number of samples in pcal window.
- f_pcal
- pcal tone separation [Hz].
Limitations / TO DO:Currently only LSB, add USB.Change int for float.Offset untested.
