Programs and commands used:

- yodat:  to obtain data from the Yohkoh directory
- write_gif: writes compressed images to files
- read_gif: reads contents of .gif format image file and returns the image and color table vectors in IDL variables
- TVRD: reads image pixels back from display device in one variable
- Image2movie: takes array of images and places them in a new array that can be read through stepper as consecutive images. It creates three things: .gif file, _mthumb.gif file, and _micon.gif file.
- XV: displays .gif files under host terminal
- Xanim: displays .mpg files under host terminal
- Rebin: resizes images by expanding to an integer multiple of the original size, averages multiple points in shrinking array
- Congrid: resizes image arrays to any arbitrary size
- SXT_prep: preps image arrays by doing a series of procedures, such as decompressing, measuring dark data, subtracting dark current,  measuring stray light, subtracting stray light,  normalizing the exposure duration, displaying the image, and allowing the image to be manually aligned.
- SXT_DN_UNC: preps the uncertainty from the image arrays in the same way as SXT_prep
- Kill_index: removes "bad/unwanted" frames from image array of prepped data and leaves the remaining ones in a new array.
- mk_regrot.pro: program made to rotate regular (or any data arrays) prepped images to a specified degree.
- mk_difmovierun.pro: program made to subtract frames in an array at a running difference of consecutive frames (one subtracted from the next one).
- mk_difmovieabs.pro: program made to subtract frames in an array at an absolute difference by subtracting the very first image from all remaining frames.
- SXT-TEEM: takes images and makes a map of the temperature and emission measure of the image by combining two images close in time of two different filters.
- teem_movie.pro: outputs temperature and emission measures from specified indexes, data arrays and filter number given in the format of listing the frame number f1ss=[0,...].  (found not to be as useful as the following adjusted program)
- teem_moviefiltwhere.pro: used to make outputs of temperature and emission measures from two specified numbered filters and uses the data arrays and indexes for input.  The program calls the filters from the data inside the program.  *** Used to make all temp and em movies***
- mk_stack2.pro: program that makes stacks 1 pixel wide from an array of data images, allows user to point and click in stepper or write in x and y coordinates for the stacks, it takes the average of the x coordinates for the single pixel on the x axis,  displays the stack in a window.
- mk_stackwidepix2.pro: program that makes stacks 5 pixels wide from an array of data images, it takes the average x coordinate and then adds 2 more to each side of that for the 5 pixel span, it has the same remaining properties of the previous program.
- timeticks.pro: program used to list the time ticks in a format of 'hour:minute:second' in Universal Time.
- mk_stacknew_ticks.pro: program that makes stacks with time ticks (using timeticks.pro) from the index of the data array.  A pixel width of 1 or 5 can be chosen in the input manually.
- mk_stacknew_tickstimes.pro: adjusted program of the previous program to properly include the times of the index if they belong to more than one day. Can be used for any flare to make stacks with time ticks.  (also uses timeticks.pro within the program)
- x2jpeg.pro: reads an image off the screen using tvrd() and saves it to a .jpg file using write_jpeg.
- x2gif.pro: reads an image off the screen using tvrd() and saves it to a .gif file using write_gif.   **Used for most .gif images**
