• A trend filtering algorithm for wide-field variability surveys (2004, neutral): “Although current sophisticated data reduction techniques (e.g., Differential Image Analysis by Alard & Lupton 1998; Alard 2000) may help to reach the near photon noise limit and minimize systematic effects, the latter seems to be never eliminated completely.”
• THE LOCATIONS OF SHORT GAMMA-RAY BURSTS AS EVIDENCE FOR COMPACT OBJECT BINARY PROGENITORS (2013, methodology): “If the position of the afterglow is contaminated by host galaxy light in the discovery image, we perform image subtraction using the ISIS package (Alard 2000) relative to latetime observations when the afterglow contribution is negligible.”
• A DECADE OF SHORT-DURATION GAMMA-RAY BURST BROADBAND AFTERGLOWS: ENERGETICS, CIRCUMBURST DENSITIES, AND JET OPENING ANGLES (2015, methodology): “To assess any fading between the two epochs, we perform digital image subtraction for each burst and filter using the ISIS software (Alard 2000).”
• The ASAS-SN catalogue of variable stars I: The Serendipitous Survey (2018, methodology): “ASAS-SN is primarily a transient search and makes use of the ISIS image subtraction pipeline (Alard & Lupton 1998; Alard 2000) to process images.”

• PROPER IMAGE SUBTRACTION—OPTIMAL TRANSIENT DETECTION, PHOTOMETRY, AND HYPOTHESIS TESTING (2016, methodology): “Since the convolution operation is local, it is straight forward to incorporate a spatially variable PSF into any subtraction method (e.g., Alard 2000).”
• The Kilodegree Extremely Little Telescope (KELT): A Small Robotic Telescope for Large‐Area Synoptic Surveys (2007, methodology): “Once a template and DAOPHOT star catalog with baseline instrumental magnitudes have been created, the second step is to process the images with the ISIS image subtraction package (Alard & Lupton 1998; Alard 2000).”
• A NEW CLASS OF LUMINOUS TRANSIENTS AND A FIRST CENSUS OF THEIR MASSIVE STELLAR PROGENITORS (2008, methodology): “To generate lightcurves, we used the difference imaging analysis package ISIS, based on the techniques of Alard & Lupton (1998), Alard (2000).16 For a discussion, see Hartman et al. (2004).”
