# Astronomical Observation Tools
|
|
|
|
Astronomical Observation Tools (Astrobs Tools) is composed of:
|
|
- SCOPE: a code to get the sky coordinate limits from observation constraints;
|
|
- EQUATOR: a software to organize targets before observations;
|
|
|
|
and the following extractors:
|
|
- HPMS: High Proper Motion Stars (Simbad Extractor);
|
|
- NGC: New General Catalogue (VizieR Extractor);
|
|
|
|
## Requirements
|
|
|
|
Astrobs Tools requires `Python 3.10` or newer
|
|
|
|
## Setup
|
|
|
|
First step is to initialize a virtual environment for the software with:
|
|
```
|
|
python3 -m venv ./venv
|
|
```
|
|
|
|
Then install the required packages with:
|
|
```
|
|
source activate.sh && pip install -r requirements.txt && deactivate
|
|
```
|
|
|
|
You may also need to authorize the execution of Astrobs Tools with:
|
|
```
|
|
chmod u+x Astrobs-Tools.sh
|
|
```
|
|
|
|
## Usage
|
|
|
|
To launch Astrobs tools, simply execute:
|
|
```
|
|
./Astrobs-Tools.sh
|
|
```
|
|
Then select the desired code
|
|
|
|
### SCOPE
|
|
|
|
1. Select a location (available location: ObAS, OHP) — default: (last one)
|
|
2. Date of observation `[YYYY-MM-DD]` - default: today
|
|
3. Begin time of observation `[hh:mm format, UTC]` — default: astronomical twilight
|
|
4. End time of observation `[hh:mm format, UTC]` — default: astronomical twilight
|
|
5. Minimum altitude above horizon `[deg]` — default: 50°
|
|
6. Minimum declination around the north `[deg]` — default: 30°
|
|
7. Observation window before crossing the meridian `[h]` — default: 4h
|
|
8. Observation window after crossing the meridian `[h]` - default: 2h
|
|
|
|
Observation parameters are then printed
|
|
|
|
- Write output to file `[yes/no]` — default: no
|
|
By default, the file is saved in the Output directory, with the name `YYYY-MM-DD_Location.cfg`
|
|
|
|
### EQUATOR
|
|
|
|
First, select a configuration file (if none, default is selected).
|
|
Then, select the action you wish to perform.
|
|
|
|
Available commands (not case sensitive):
|
|
- `help`, `h`, `?`: show this page
|
|
- `quit`, `exit`, `q`: quit the current code (WARNING: this does not save the current state!)
|
|
- `write`, `save`: write the current table in a file
|
|
(no options available yet)
|
|
- `read [filename]`, `open [filename]`, `load [filename]`: loads the file "filename" in the current table (no additional options available yet)
|
|
- `calibration`, `calib`: adds a calibration in the target list
|
|
- `simbad [object name]`, `object [object name]`:
|
|
add an object from simbad
|
|
- `search [ra] [dec] [radius]`, `region [ra] [dec] [radius]`: search a region centred on the ra/dec coordinates, with a given radius (ra is given in hour, dec in degree and the radius is any specified unit,, e.g. `search 01:03:40 35:40:20 30'`)
|
|
- `manual [name] -s [seq]`, `add [name] -s [seq]`: manually add a target (only the name and the sequence are available for now)
|
|
- `sequence`, `seq`: computes the sequence order for each
|
|
target
|
|
- `check`: check if all targets are in the observation field
|
|
- `plot`, `graph`: creates a graph with all the targets observation date and time
|
|
|
|
General actions:
|
|
- `cancel`, `back`: cancels the current action
|
|
- `yes`, `y`, `1`: yes
|
|
- `no`, `n`, `0`, or anything else: no
|
|
- `all`, `*`: select all
|
|
- `done`, `ok`: confirm, save the current state and quit
|
|
|
|
### Extractors (HPMS, NGC)
|
|
|
|
Extractors are small codes to query databases in order to extract a table of potential targets. Using them is often straightforward, and their result is always written in the `Output/` directory.
