# **CanUVIT** > To check whether a field can be safely observed with UVIT. <p align="center"> <img src="https://i.imgur.com/b0hoB04.png" width="400"/> </p> You can install the CanUVIT Python package using the following command. ```bash pip install canuvit --upgrade ``` > **IMPORTANT:** Even if you have CanUVIT already installed, make sure you use the latest version by running the above command. Current version of CanUVIT is shown on the badge below: <br> <a href="https://pypi.org/project/canuvit/"><img src="https://img.shields.io/pypi/v/canuvit?style=for-the-badge"/></a> After installation, you can run CanUVIT on a Python command prompt or as a script. For example, if your primary instrument is UVIT and the RA, DEC coordinates of the field are (12:12:12, 12:12:12), you may run the CanUVIT package as follows. ```python >>> import canuvit >>> canuvit.observe('uvit', '12:12:12', '12:12:12') ``` > **Note:** In general, `canuvit.observe(instrument, RA, DEC)` where the `instrument` can be either 'uvit', 'sxt', 'czti', or 'laxpc' and `RA` and `DEC` field coordinates should be in sexagesimal format. For the above example, you should get an output as shown below. Please also check the working directory for the output GALEX images with sources marked in the primary instrument field of view. ``` ========================================================= Payload: uvit, Coordinates: 12:12:12, 12:12:12 ========================================================= ### VIS sl_no ra_hms dec_dms mag B-V SpecType VIS3 VIS2 VIS1 ND1 BK7 ----- ---------- ----------- ---- --- -------- ------ ----- ----- ---- ------ 1 12:11:52.8 +12:07:47.5 11.1 0.9 K1 1333.0 124.4 88.6 29.7 1624.9 2 12:12:22.9 +12:17:23.9 11.1 0.8 K0 1296.7 121.0 86.2 28.9 1580.6 3 12:11:35.0 +12:12:04.6 11.4 0.5 F5 1457.4 234.9 180.9 32.8 1915.2 4 12:11:01.7 +12:08:35.9 11.9 0.7 G5 754.3 89.1 69.2 16.8 950.9 5 12:11:11.5 +12:03:14.0 12.2 0.3 F0 803.1 143.5 101.4 18.2 1061.7 6 12:12:05.5 +12:19:09.8 12.3 0.8 K0 452.9 42.3 30.1 10.1 552.1 Safe filters: ['VIS3', 'VIS2', 'VIS1', 'ND1', 'BK7'] FUV observations seem to be absent!

Further, for good tracking of the aspect, there should be at least two stars within a 12 arcminute radius of the target with >30 counts/second (for good S/N) and <1000 counts/second (to avoid saturation) in the chosen filter. Please also avoid configuring multiple VIS filters. Two additional functions are also available, which takes the same input arguments as `canuvit.observe()`. * `canuvit.observe_VIS()`: to find safe VIS filters. * `canuvit.observe_UV()`: to find safe UV filters. ### Command Line Interface After installation with pip, you can also access CanUVIT from the command line. Here's an example: ```bash canuvit -i uvit -r "12:12:12" -d "12:12:12" ``` The help page of the command-line tool can be accessed as follows: ```bash canuvit -h ``` ``` Usage: canuvit [OPTIONS] Program to check if a given coordinate can be safely observed using UVIT. Example usage: canuvit -r "13:12:14" -d "-14:15:13" Options: --all Check safety for all filters. [default: all] --vis Check saftey for only visible filters. --uv Check safety for only UV filters. -r, --ra RA Right ascension of the coordinate. Format: hh:mm:ss[.ss] e.g. "00:54:53.45" [required] -d, --dec DEC Declination of the coordinate. Format: [-]dd:mm:ss[.ss] e.g. "-37:41:03.23". [required] -i, --instrument [uvit|sxt|czti|laxpc] Instrument to check for. [default: uvit] -v, --verbose Increase output verbosity. --version Show the version and exit. -h, --help Show this message and exit. ``` ### Acknowledgements CanUVIT depends on the following web tools and API for its functioning. * Bright Source Warning Tool (https://uvit.iiap.res.in/Software/bswt) * Exposure Time Calculator (https://uvit.iiap.res.in/Software/etc) * MAST API (https://mast.stsci.edu/api/v0/) ### Requirements CanUVIT works with Python 3.6 or later. CanUVIT depends on the following packages: * astropy * astroquery * beautifulsoup4 * click * matplotlib * numpy * requests
