File types for input object list


You can use the following types for your target list.

     OPE file
You can use OPE files for Subaru SOSs/Gen2.
  • If OPE load some PRM file, in which stores standard stars, they are also automatically loaded. Or you can merge any PRM files manually (Menu→FileMerge PRM).
  • If you are using hskymon with XMLRPC option on Gen2 system, you can synchronously open OPE files opened in IntegGUI (Menu→FileSync OPE with IntegGUI).

Each target must be defined with its OBJECT (name), RA, DEC, and EQUINOX within <PARAMETER_LIST> section of OPE files as follows.
       <PARAMETER_LIST>  
       TGT_V5668Sgr=OBJECT="V5668 Sgr" RA=183656.87 DEC=-285539.30 EQUINOX=2000.00
       TGT_HD164536=OBJECT="HD164536" RA=180238.62 DEC=-241519.39 EQUINOX=2000.00
       TGT_sigSgr=OBJECT="sig Sgr" RA=185515.93 DEC=-261748.21 EQUINOX=2000.00
       TGT_HD149757=OBJECT="HD149757" RA=163709.54 DEC=-103401.52 EQUINOX=2000.00
       TGT_HD184915=OBJECT="HD184915" RA=193653.45 DEC=-070138.92 EQUINOX=2000.00
       TGT_V339Del=OBJECT="V339 Del" RA=202330.73 DEC=+204604.10 EQUINOX=2000.00
          ....................................
       </PARAMETER_LIST>


     CSV (comma separated) list
You can also use CSV list text files for your target list like
	Object Name, RA(hhmmss.ss), Dec(ddmmss.ss), Equinox, Free comments
. For example,
	HD94028     ,105128.1 ,+201639.0 ,2000,  [comments]
	BD+36 2165  ,111248.0 ,+354343.9 ,2000,  Mv=8.4  Fe/H=-2
	HD97916     ,111554.2 ,+020512.1 ,2000,  Mv=10.2 Fe/H=-2
	BD+51 1696  ,114635.2 ,+505254.7 ,2000   
	BD-13 3442  ,114650.7 ,-140643.5 ,2000,
          ....................................
Load CSV list files : Menu→FileOpen(Merge) CSV List.

     Non-Sidereal Tracking File (TSC format)
Non-Sidereal tracking files for TSC are also loadable.

Please put TSC files in an appropriate directory (maybe in the same directory where your OPE files locate) and load them from the menu.
Files must follow the format described in this page.
You should use Geocentric coordinate in TSC files. They would be automatically converted into topocentric in the program. Therefore, coordinates displayed in Object List Window or other parts of hskymon would not be exactly same as ones described in Non-Sidereal tracking files.

     Non-Sidereal Tracking File (JPL HORIZONS format)
hskymon can also load NASA JPL HORIZONS output files.
Please note that you should set
	"Ephemeris Type" = OBSERVER
	"Observer Location" = Geocentric
	"Table Settings" = 1. Astrometric RA & Dec, 20. Observer range
for your input. Either calendar date or JD is acceptable for date format.
From the main menu, HORIZONS files can be converted into the TSC format.

        		    TGT_NGC3242_TT=OBJECT="NGC 3242 TTGS" RA=102446.40 DEC=-183918.95 EQUINOX=2000.00
      • or a CSV text file.
        		         NGC 3242, 102446.11, -183832.64, 2000.00
        		    NGC 3242 TTGS, 102446.40, -183918.95, 2000.00, added via FC (NGC3242)


     Dithering pattern display (for HSC)
Clicking HSC Dithering Parameter button (15) on Finding Chart Window, HSC Dithering Parameter dialog will be popped up.
In this window, you can set parameters for HSC dithering pattern and display it on the finding chart.
HSC Dithering Parameter Window
  • "+" marks on the chart correspond to the target position without RA/Dec offset.
  • HSC CCD chips are displayed without field curvature calculation. Therefore, the chart may include a little bit of shift on the outer edge of the FOV. Please use HSCPlanner for more careful field checks.

     How to load Non-Sidereal targets
For non-sidereal targets (planets, asteroids, comets etc.), both of TSC and JPL HORIZONS format tracking files are loadable as targets in hskymon.
Because hskymon does not automatically load them described in loaded OPE files, you have to load each of them manually from the menu. During observations, you should put tracking files in the same directory of Gen2 system where your OPE files are stored.
The tracking coordinates must be calculated with Geocentric. Inside of hskymon, those coordinates are translated into Topocentric. Therefore, coordinates shown in Object List Window or other parts in hskymon should not exactly coincide with those described in tracking files.
After loaded Non-Sidereal targets, you can confirm calculation time ranges of each file in Note section of Object List Window. When the current / set time & date is out of its calculation time range, the object is displayed with "x" mark in Main Window.
Non-Sidereal targets : Main Target TAB     Non-Sidereal targets on hskymon
In Finding Chart Window, you can check orbits of Non-Sidereal targets.
Finding Chart for Non-Sidereal targets
Using Menu → Non-SiderealConvert HORIZONS to TSC, JPL HORIZONS format files can be translated and saved into TSC format ones.


     Proper motion
If a target is suspected to have a proper motion, you can check it on the Finding Chart Window using Database query (10) in SIMBAD (or USNO-B, GAIA).
Proper motion of Baranard star
The green line and dot show the proper motion from J2000 to the observing date (the date specified in Main Window).
OPE Def in Object List Window : Finding Chart TAB (16) makes a definition considering the shift by proper motion (The left green dot in the image).


     How to compile from source code (UNIX)
  1. Required libraries to build hskymon are
    Gtk+2(>2.24) or Gtk+3 (>3.22), libxml2, openssl, json-c, and xmlrpc-c (only w/XMLRPC option) and their developer's environment.
  2. get the source code
    1. download .tar.gz and extract it, and change directory.
    2. If you download the source code via git
        % git clone https://github.com/chimari/hskymon.git
      Then,
        % cd hskymon
        % touch configure configure.ac aclocal.m4 Makefile.am Makefile.in
      This is necessary to avoid errors on aclocal.
  3. ./configure
    [option]
       --with-gtk3     : use Gtk+3 instead of Gtk+2
       --with-xmlrpc   : make w/xmlrpc to get telescope status in Gen2
       --with-win32    : make for Windows (32bit/64bit)
       --with-gtkmac   : make w/gtk-mac-integration for mac OS
       --with-maintain : designate deprecated functions (for maintainer)
    If you compile with XMLRPC option (to connect with Gen2 status server), you should edit DEFAULT_RO_NAMSERVER in
      gen2.h
    to the effective address of Gen2 status server (You must ask it to Subaru OCS team, only in the case that you need it.).
    If you find some errors concerning aclocal etc. stop the configure script, please try
    ./autogen.sh
    instead of ./configure .
  4. make
  5. sudo make install
    Only an executable binary, "hskymon", is required to run the program.


     How to make Debian package from source code
  1. Please prepare required libraries to build from the source code listed above.
  2. Get the source code and extract it.
  3. % cd hskymon-x.x.x/debian/
  4. % debuild -us -uc -b
  5. Then, a .deb package will be created at the same level directory where the source (hskymon-x.x.x/) is located.


     How to make RPM package from source code
  1. Please prepare required libraries to build from the source code listed above.
  2. Please also prepare rpmbuild environment in your linux system.
  3. % cd ~/rpmbuild/SOURCE/
    Download the source code (.tar.gz) into the SOURCE directory.
  4. % cd ../SPEC/
    Extract hskymon.spec into the SPEC directory.
    % tar zxvf ~/rpmbuild/SOURCES/hskymon-x.x.x.tar.gz hskymon-x.x.x/hskymon.spec --strip=1 -C  ~/rpmbuild/SPECS/
  5. Build RPM.
    % rpmbuild -bb --clean ~/rpmbuild/SPECS/hskymon.spec
  6. Then, you will find a .rpm package in ~/rpmbuild/RPM/(your architecture)/ .
