ticguide: quick + painless TESS observing information
Complementary to the TESS observing tool tvguide (see also WTV), which tells you if your target will be observed by TESS (i.e. on silicon, guaranteed FFI coverage), this tool tells you if your target was* observed by TESS in other cadences (i.e. short- and fast-cadence). * this draws only from available MAST observations and therefore does not inform you of upcoming sectors.
Installation
You can install using pip:
$ pip install ticguide
or via the github repository:
$ git clone https://github.com/ashleychontos/ticguide.git
$ cd ticguide
$ python setup.py install
You can check your installation with the help command:
$ ticguide --help
usage: ticguide [-h] [--file path] [--out path] [--path path] [-p] [-s]
[--star [star [star ...]]] [-t] [-v]
optional arguments:
-h, --help show this help message and exit
--file path, --in path, --input path
input list of targets (requires csv with 'tic' column
of integer type)
--out path, --output path
path to save the observed TESS table for all targets
--path path path to directory
-p, --progress disable the progress bar
-s, --save disable the saving of output files
--star [star [star ...]], --stars [star [star ...]], --tic [star [star ...]]
TESS Input Catalog (TIC) IDs
-t, --total include total sectors per target per cadence
-v, --verbose turn off verbose output
Examples
When running the command for the first time, the program will need to make a local copy of all observed TIC IDs (which is currently ~150 Mb, so this will take a few minutes depending on your computer). You have an option to disable the auto-saving of this table and it will still pass the pandas dataframe, but it will need to make this each time you run the program. Therefore if you use this often enough, I recommend letting it save a local csv file.
Example output when running ticguide for the first time with the default settings:
$ ticguide --star 141810080

^^ as shown by the progress bar, the program iterated through 64 bash scripts. This makes sense since if TESS is currently on sector 45, which means there are 45 short-cadence and 19 fast-cadence sectors available (-> 45+19=64).
Command line easily handles multiple TIC IDs by appending them to a list:
$ ticguide --star 141810080 441462736 188768068

If you have many many targets, you can instead provide a single-column txt or csv file, with targets listed by their TIC id (one entry per line).
$ head todo.csv
tic
141810080
188768068
441462736
A boolean table is created using the provided list of targets (TICs) as the table indices and all unique combinations of the cadences and sectors as columns, where True would mean a given TIC was observed in the listed cadence and sector. For example, the column "S027" means short-cadence sector 27 observations, whereas "F027" is the same sector but in fast cadence.
