We previously made available data on +the four clusters M35, M67, Ruprecht 147, and NGC 6530 (the Lagoon Nebula region). We are now releasing five new sets of images, +all obtained during the Campaign 9 observations of the galactic bulge. + +While the data for all of these regions have long been served on MAST, until recently they were only available as a disconnected set +of smaller Target Pixel Files (TPFs) because the spacecraft stored these observations in small chunks. With [this new +release](https://archive.stsci.edu/prepds/k2superstamp/), we have stitched these TPFs together into spatially contiguous FITS images +(one per cadence) to make their scientific analysis easier. In addition, each image has been fit with an accurate WCS solution so +that you may locate any object of interest via its right ascension and declination. + +The process of stitching and astrometric calibration is described in a +[companion RNAAS article](http://iopscience.iop.org/article/10.3847/2515-5172/aaac30/meta). + +The release of these superstamp FITS images makes the analysis of crowded galactic bulge regions simpler, and we hope it will lead to +new discoveries. We note that the format of the images (data structure and headers) mirrors that of Kepler/K2 and TESS mission full +frame images. This was not the case for our original K2Superstamp cluster products, and so future versions will update them as well +as add new sets of data for the cluster M67, which was re-observed in K2 Campaigns 16 and 18. We also plan to release superstamp +images for the two clusters NGC 6819 and 6791 that were observed in the Kepler prime mission. + +K2 Superstamp region
