Abstract: DASHA-2 is the next iteration of the DASHA package (Smirnov & Ipatov 1995) for processing data produced by the DAOPHOT II PSF photometry software (Stetson 1987, 1992). The original package was implemented under the pcIPS image processing system (Smirnov & Piskunov 1995), whereas DASHA-2 is completely written in IDL. The package is tailored for the reduction of large batches of CCD observations, where the same field is observed at different exposures and in different photometric bands. DASHA-2 is currently in heavy use at the Institute of Astronomy, where it is routinely employed to reduce observations of globular clusters, resulting in photometric data for upwards of 15,000 objects in a single field.
