Verbinal

Verbinal brings the Canadian Astronomy Data Centre (CADC) and the CANFAR Science Platform to your iPhone and iPad. Open a FITS image or a spectral cube from anywhere, check that it is right, and share it — no account needed. Sign in with your CADC account to follow your sessions, your storage and your code wherever you are. NO ACCOUNT NEEDED • View and verify FITS images and spectral cubes from Files, Mail, AirDrop or your storage. • Two sample files to try at once: M31 from Hubble, and GN-z11 from Webb. FITS VIEWER • Pinch to zoom and turn (North Up snaps into place), double-tap for fit or 1:1, and hold for a loupe with the pixel's value and sky position. • A compass from the image's WCS, a scale bar, and the crosshair's coordinates — tap to copy them. • Adjust: automatic, 99.5 % or min–max cuts, a histogram with draggable black and white points, five stretches and a choice of colour maps. • Verify: DATASUM and CHECKSUM from the file's own bytes, statistics and the WCS; the whole header, searchable; every HDU. • Hold Compare to blink two images aligned on the sky. • Share a picture of the view, or the file itself. CUBE VIEWER • Step through the channels with the cube's mean spectrum under your thumb: a tick for each channel, a firmer one on a peak. • Hold a spaxel to read its spectrum; drag along it to move the channel. • Moment 0 maps, and a 3D volume view on iPad and recent iPhones. • Verify the spectral axis, the values and the blank channels. YOUR FILES, ON THIS DEVICE • Open a file header first: its HDUs and cards before any pixels move, even straight from your storage. • Keep files on the device, see what Verbinal uses, and clear what you no longer need. WITH A CANFAR ACCOUNT • Portal: the platform's load at a glance; your sessions, with renew, events, logs and delete; launch a new session or relaunch a recent one; your batch jobs; and what needs your attention. • A reminder before a session expires. • Your Storage: browse, upload, download, keep, make folders and delete, with your quota. • Compute: run Python or Bash on your own CANFAR session, follow each run, and open the files it writes. PRIVATE • No analytics, no tracking. Your credentials stay in the iOS Keychain, and the app talks only to CADC and CANFAR, over HTTPS. • In English and French, with VoiceOver support. The viewers and your files need no account. Portal, Compute and Your Storage need a CADC/CANFAR account.
