ticguide : quick TESS data and observing info

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.

UPDATE: New 0.5.2 version will even download the data for you!

Installation

You can install using pip:

bash $ pip install ticguide

or via the github repository:

bash $ 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 usage: ticguide [-h] [--version] [--download] [--fast] [--fileinput str] [--fileselect str] [--fileall str] [--ll int] [--path str] [--progress] [--save] [--short] [--star [int ...]] [--totals] [--verbose]

Examples

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

              TIC 141810080                   

26 sectors(s) of short cadence -> observed in sector(s): 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,

11 sectors(s) of fast cadence -> observed in sector(s): 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39
```

^^ 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:

``` ♡ ~/tess % ticguide --star 141810080 441462736 188768068

              TIC 141810080                   

26 sectors(s) of short cadence -> observed in sector(s): 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,

11 sectors(s) of fast cadence -> observed in sector(s): 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39

              TIC 441462736                   

2 sectors(s) of short cadence -> observed in sector(s): 2, 29

1 sectors(s) of fast cadence -> observed in sector(s): 29

              TIC 188768068                   

11 sectors(s) of short cadence -> observed in sector(s): 17, 20, 24, 25, 26, 40, 47, 50, 51, 53, 54

6 sectors(s) of fast cadence -> observed in sector(s): 40, 47, 50, 51, 53, 54 ```

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.
