# ASTApy
Thin wrapper around ASTAP CLI
download astap cli and some database stars.
here https://www.hnsky.org/astap.htm#astap_command_line
# Installation
## ASTAP
Go here: https://www.hnsky.org/astap.htm
Download the cli for your os.
Save the binary in nice location, ex. create this `~/.local/astap`
Save this location in PATH: `export $PATH=~/.local/astap:$PATH`
Rename the cli executatble to `astap`
### Database
download start database, say `D50`. Unpack it, store the data in the same dir for astap cli executable.
### Test CLI
type `astap --help`, it will show the help page.
## ASTApy
Install `Astapy` from PyPi: https://pypi.org/project/astapy/
#### Note
It would be better to install it in `venv`.
# Use
Example usecase
```python
from pathlib import Path
from astapy import Astapy, Angle
# the fits file location. Define the file path using Path from pathlib
file = Path("./data/test.fit")
# define initial coordinate for searching, optional, default to ra=0, dec=0
dec = Angle.from_deg(d=29, m=39, s=49)
ra = Angle.from_hour(h=6, m=30, s=49)
# fielv of fiev of the image, must be close to make the algorithm effective
fov = Angle.from_deg(d=0.18)
# search radius
r = Angle.from_deg(d=10)
# initial Astapy
a = Astapy(file=file, dec=dec, ra=ra, fov=fov, r=r).args(z=1)
# run it and show log
wcs = a.run(log=True)
# print the wcs header value
for val in wcs:
print(val)
```
### astap cli location
if your `astap` has different name or location, you can configure it. Call this function at the top level.
Let's say your astap cli executable is `astap_cli`
```python
from astapy import config
config({
'exe': 'astap_cli'
})
```
