AstroDrizzle for HST images.
_Issue [HLA-463](https://jira.stsci.edu/browse/HLA-463) was created on JIRA by [Warren Hack](https://jira.stsci.edu/secure/ViewProfile.jspa?name=hack):_ Despite having enough GAIA sources in the field, only a smaller than expected fraction of WFC3/UVIS fields actually get aligned to...
Another way of verifying relative alignment could be to count the number of cosmic rays detected in an image, and comparing that to the other astrometric solutions. Since the default...
These tasks were written prior to 'devutils' being developed, and should be moved into that directory for dev use only, leaving the top level for end-user tasks only. - config_testbed.py...
Another layer of protection against spurious or incorrect apriori solutions provided by the astrometry database would be to check that the new solution does not modify the CRVALs by more...
Evaluation by M. Cara of the alignment residuals for j6d508020 (as an example) produced by the new tweakwcs-based pipeline alignment processing indicates that the residuals in Y from one chip...
Also, reconsider the name of the catalog as it currently includes a detector and flt or flc substring. However, this file represents the entire single visit which may use multiple...
In the meeting of 23 January 2020, Rick gave us a demonstration of the software he has been working on for comparing HLA and HAP catalogs. One of the datasets...
In my notes of 21 November 2019 (Sprint review), I have a seemingly random note that indicates Grism data can have _a priori_ solutions. I have no other context for...
Standard pipeline processing includes (as of HSTDP 2019.5) comparisons of drizzle products to flag obvious errors in the alignment that would result in smeared or double exposures. The comparisons implemented...
