### How to use the online plotter to show mapping mbfits ###
# Mode: specified subscans/ complete scans##
# File Filter: EFFBG*.fits ## to choose fits files
# FeBe: S45mm-OPTOCBE ## select backends
# average mode: average subscans (binned)
# continuum baseline order (removal): -1
# To show maps:
# mapping: (select) compute maps
### How to use Peter Mueller's toolboxes which are convenient for quicklook####
# slogin observer4 -l ygong
### Toolbox (setting in the bash):
#alias toolbox='/homes/peter/Test_Toolbox2/toolbox2.py'
#alias nod3='/homes/peter/New_NOD3/nod3.py'
#export PYTHONPATH=/homes/peter/New_NOD3/lib/python2.7/site-packages/
### A detail describtion of toolbox can be found via
### https://eff100mwiki.mpifr-bonn.mpg.de/doku.php?id=information_for_astronomers:user_guide:reduc_pointing
### toolbox plot='/xs' (or '/ops') febe='S45mm-SPECPOL' scan=7173 waterfall spcreate (or spmask=spmask)
# right mouse to zoom in
# left click + space --> flag data ---> may choose "repair" to repair the data
### stard nod3 to quicklook the data

########### Polarimeter test ########
# During the polarimeter test of linear polarized signals, Q is 50% of I, try to change attenuation power of ADC (+3dB)
# It works fine afterwards.
############ observation strategy ##########
## time: 13.02 2018 2-17 LST, 17-8 CET
## Goal, 3C273, 1' sampling, 2 directions (AZ/EL mapping), 30'x30' size
## Switch between polarized and unpolarized sources for a range in parallactic angles
## 10'x10', latitude mapping
## Polarized sources : 3c138, 3C286, W44 (18:56:10.650, 01:13:21.30 J2000)
## unpolarized sources: 3C147, 3C295, NGC7027
## A long stripe through W3 (L=133.9476, B=1.0650), 15' wide to convolve the stripe to the Urumqi resolution.
## frequency setups: low frequency 4-6 GHz, 1024 channels
