About this field
A wide-survey tile centred on the COSMOS region, where three decades of multiwavelength imaging give Roman's photometric redshifts an unusually strong calibration anchor.
Product status
A pre-flight simulation product. Generated on the ground to build and test the calibration pipeline before launch — useful for developing analysis code, but it is synthetic, not sky.
Exposure
Pointing
Band
J-band; a core survey filter.
Access

Source positions, colours and crowding are derived from the field's galactic latitude and character and from the band's pivot wavelength, and every exposure of a field draws the same sky so dithers line up — but none of it is data from the telescope.
