ScottJohn Hutchison was our son, brother and friend. He was best known to most as the lead singer and songwriter in the band Frightened Rabbit. Through his music and art Scott made tiny changes that had a big impact. His honesty and openness about his own mental health inspired people from all walks of life. In May 2018, at the age of 36, Scott died by suicide.
The Tiny Changes family is growing all the time. We are creating worthwhile projects from money raised, we are asking people to tell their stories as we have told ours, and we are pushing the boundaries to raise awareness of what needs to be done to make things better.
Tiny Tim (Krist & Hook 2011) is a point spread function modeling tool developed for HST. Details of the code's operation, configurable parameters, and products are given in the Tiny Tim User's Guide (Krist & Hook 2004, version 6.3). Tiny Tim is no longer maintained or supported by STScI; a final version of the source code is hosted "as-is" on Github, for legacy purposes.
Presently, we do not recommend using Tiny Tim for WFC3 data as it relies on outdated optical models (WFC3 ISR 2008-14, published before WFC3 was installed). As an example, WFC3 ISR 2014-10 found significant errors in the WFC3/IR Tiny Tim model. Our team has focused recent efforts on building empirical PSFs and a database of observed PSFs.
For external users, we do not encourage the use of Tiny Tim nor support the software, as it is "available but unsupported." Members of the STIS team currently do utilize Tiny Tim for specific internal purposes.
For coronagraphic observations requiring PSF subtraction, users are advised to follow the recommendations for obtaining contemporaneous PSF calibrators in Section 12.11 of the STIS Instrument Handbook.
We do not support Tiny Tim. For users interested in generating PSFs for ACS, we suggest looking at the effective PSF utility described in the photutils documentation. For additional background on this utility, please see Anderson & King (2000) and WFC3 ISR 2016-12. Additionally, see ACS ISR 2017-08 for comparisons to Tiny Tim generated PSFs.
See the Tiny Tim User's Guide for a description of the output products. For ACS and WFC3, PSFs are calculated for both undistorted (tiny2 output) and distorted (tiny3) images. Only the tiny3 distorted image is sampled at the detector resolution. This product corresponds to the images supplied by the pipeline as "_flt" files. For the other instruments, the distortion is much less and has not been considered in Tiny Tim.
The generated PSFs can be useful for image simulation and observation planning, or to indicate the level of PSF variability over the field and with time, or for small aperture photometry. For PSF subtraction where details of the outer portions of the distribution are important, and for other cases where accurate PSF characterizations are needed, these modeled PSFs may lack suitable accuracy, and empirical PSF techniques should be considered when practical.
Refinement of the models may enable their more effective use for other data reduction tasks. PSF fidelity will also be found to vary among instruments. For example, the ACS Tiny Tim PSF is believed to be better modeled currently than the WFC3.
For WFC3, Tiny Tim uses aberration coefficients that are derived from the as-built optical ray-trace model, as a function of field position. While the ground test and on-orbit image quality generally matches expectations, no attempt was made to adjust the aberration coefficients used by Tiny Tim to better describe the observed field dependence. Tiny Tim also uses blur kernels to describe the effects of charge diffusion and, for the IR channel, inter-pixel capacitance. The IR and wavelength-dependent UVIS kernels were updated from those listed in WFC3 ISR 2008-14, to better match pre-launch measurements. These updated kernels are described in WFC3 ISR 2008-40 and WFC3 ISR 2008-41.
Probably like you, I'm that person who is constantly coming up with lots of little project ideas. Whether that be ideas for apps, websites, games, businesses; whatever. I have them all stored on a list in my phone, and I know you probably have one of those lists too.
The goal of this website is to try and explore as many of these ideas as I can. I'm not one for new year's resolutions, but I do seem to get into a habit of setting goals around my birthday. I turned 25 on May 17th 2020, and my goal for my 25th year on earth is to try at least one of these tiny project ideas every few months and see what happens. If they can make some money too, that'd be great.
There have been multiple delays and about-faces, over everything from the way the state is funding the units to the ability of local cities and counties to find places to put them. The state has suggested the delays are the fault of local governments. But tiny homes have failed to materialize even when local leaders moved quickly to approve a project site.
The governor set up a big to-do when he made his tiny home promise in March of last year. He had sample tiny homes set up in the Cal Expo event center to use as a backdrop as he spoke. Local officials, including Sacramento Mayor Darrell Steinberg and San Jose Mayor Matt Mahan, flanked him to show their support and gratitude.
Of the four communities promised tiny homes, the state has made the most progress in Sacramento. In late January and early February, the state bought 155 units from BOSS, a tiny home company based in Montebello in Southern California. Those units, most of which are 70 square feet, have been built and are ready to ship to Stockton Avenue, said Kris Van Giesen, senior vice president of community development.
That move was supposed to help get more tiny homes deployed quickly, and therefore, move more people out of encampments. But CalMatters spoke with all six approved vendors, and none have received any orders through that process.
And the state insists on approving any promotional materials the vendors put out on their own, Valgardson said. After his company, Irontown Modular, accidentally posted marketing materials online prematurely, the state made them take the materials down and get approval. It took almost two months to get the green light, Valgardson said.

TINO was born and raised in Cleveland, Ohio and found his love for rhyming while attending college in Dayton. He has a unique style blending the Golden Era of hip hop with modern elements, bridging the gap between the old and new schools of the genre.
Hargett, a Dayton-based native, delivers honest and well-crafted lyrics against a diverse landscape of musical influences, including folk, country, rock, and soul. Her songs connect with a wide audience and are designed to leave a lasting impression. Hargett released her sophomore album, titled Coal Mine Canary, in 2022.
Dayton native, Erin Cannon, began her Djing journey at a young age by simply making beats with everyday utensils like pencils and a desk! Her love for music has always been apparent and she appreciates all genres of music. As she reached adulthood, her interest and curiosity grew and she fell in love, especially with hip hop. She attended class for disc jockey's in Indianapolis every Saturday which has resulted in her being booked for events every weekend all across Ohio.
serin oh was born in Suwon, South Korea, and moved to Ohio with her family at the age of six. Growing up in church, she was surrounded by gospel music in her formative years. During her time at Berklee College of Music, she discovered her love for jazz and R&B, whilst also rediscovering her Korean roots through the lens of K-Pop. oh also began her own personal journey of what it means to follow Jesus, which led her to begin storytelling through music. She hopes to uplift and spread the truth, especially to fellow secret outcasts.
Many property owners are interested in using tiny houses or tiny homes to house themselves or others. Small homes can be a creative solution to the current housing crisis by providing much-needed, cost-effective, and energy-efficient housing and may be used as temporary or permanent housing subject to corresponding permit.
