'''
Interactive tool to adjust measured phasecal phases and determine
delays. Requires a saved NPZ file containing the phasecal data.
'''
# History:
# 2017-Mar-05 DG
# First complete version
# 2017-Mar-07 DG
# Corrected sign error in Y-X delay, and now write to database
# and ACC without specifying a time (uses current time). That
# means the current time should not be too different from the
# time in the data, but I leave that up to the user.
# **Breaking News**
# The new 300 MHz correlator is working! Delays determined based
# on data from that correlator have flipped signs! So I made the
# change on saving them.
# 2017-Apr-07 DG
# Cleaned up the "show" button output, and set the default directory
# for npz files to the phasecal web directory (/common/webplots/phasecal)
# 2017-Jul-08 DG
# Added new menu item for setting the Ant 14 low-frequency receiver
# delays. These delays are written into the Ant 15 slot by the
# cal_header.dla_update2sql() routine. Note that delays for other
# antennas are not updated, even if they are non-zero (a warning is given).
# 2018-Jun-08 DG
# Relatively important change to display antenna phases with respect to
# ant 1, except for ant 1 itself, which displays baseline 1-14. This
# turns out to be a relatively minor change. Also add a checkbox to
# allow the user to mark missing antennas.
# 2020-May-02 DG
# Added some much-needed legends to the plots
# 2023-Oct-07 DG
# Add refant checkbox and ability to change the reference antenna. This is
# for the display only. The delay center reference remains with Ant 1.
