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.
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:
♡ ~/tics % ticguide --help

--verbose, -v Disable the verbose output
The program uses the MAST bulk downloads scripts to assemble a list of observed TIC ids to then generate the relevant material the user wants, whether it be the observed sectors and/or cadences or the actual data (yes, you read that right!).
CLI example (it may take a minute to run through all observed sectors, since it's a lot now):
♡ ~ % tiguide --star 141810080

^^ as shown by the progress bar, the program iterated through 84 bash scripts. This makes sense since if TESS is currently on sector 55, which means there are 55 short-cadence and 29 fast-cadence sectors available (-> 55+29=84).
Command line easily handles multiple TIC IDs by appending them to a list:

The new download feature can be seen by the second progress bar. Even if
you didn't use the download option (-d
or --download
), the program assumes
there is some interest in the selected targets and therefore creates a bash
script per target in the same way MAST provides bulk download scripts per sector!
To initialize the scripts, simply run the above command with the -d
flag:
♡ ~/tess % ticguide --star 141810080 441462736 188768068 -d
... and watch it go. To keep everything nice and neat, it will create a parent directory called 'targets' and make one folder per target, where the target's light curves will be downloaded to!
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 selected_tois.csv
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.
