O-C Calculation and Plotting

In this update:

New program called OC_plot.py and this program calculates O-C values from already determined Times of Minimum (ToM) given TESS data only at this time. The next update of this specific program will determine the O-C values for the Ball State University Observatory (BSUO).

Given these O-C and their errors, this program plots an O-C graph while differentiating between primary and secondary (i.e. different markings for each on the plot itself). The program will overlay any number of polynomial fits that the user would like and create a residual plot using the largest polynomial value entered overlaid on top of just the primary eclipses.

The program outputs ToM, eclipse number, O-C, and O-C error into a single file that the user can reference later if needed.

AIJ Night Filter Fix

In this update:

This fixes a major issue with the AIJ night filters that requested the user to enter an output file after each file path was entered. This defeated the purpose of this program. There was also a minor issue with this program where if the column length was 4 the if statement for this crashed the program because there was a missing parameter in the Boolean logic.

APASS AIJ Error Fix

In this release:

An error was found in the APASS_AIJ_comparison_selector.py file where if the final list of potential comparison stars was empty, the program would crash. The old method attempted to remedy this with an if statement but this was the main cause of the crash. Now if the that same list is empty, it will output a print statement saying that there were no comparison stars found between APASS and AIJ.

Science Image Overlay

This release adds the ability to overlay a science image with potential comparison stars and AIJ generated comparison stars to gather the corresponding APASS magnitudes for Johnson B, V, and Cousins R filters.

BJD to HJD Conversion

This update takes the TESS BJD_TDB and converts that time into HJD and outputs both times into the header of the FFI's incase a user needs either values.

IRAF Reduction

This release adds the ability to reduce science images from the Ball State University Observatory (BSUO) but currently only reduces the calibration frames but will soon reduce the science images as well in the next couple of releases.

More Minor Updates

This includes some more minor comment updates to hopefully further help the user determine which output files are going to actually be used verse which ones are just nice to have in case of calculation confirmation.

Minor Updates

Minor rearrangement updates to AIJ comparison selector code for ease of use.

TESS Night Filters Closing

Forgot to update the TESS Night Filters file to allow the user to close the program. Same exact method as the AIJ version but inserted into TESS

Allowing Inter-Program Closing

This update allows the user to close programs after typing in the number from the main menu to return to that main menu in the case of selecting the wrong number.
