The first pathfinder of the CATCH mission, CATCH-1, was launched on June 22, 2024, alongside the Space-based multiband astronomical Variable Objects Monitor (SVOM) mission. CATCH-1 is equipped with narrow-field optimized Micro Pore Optics (MPOs) featuring a large effective area and incorporates four Silicon Drift Detectors (SDDs) in its focal plane. This paper presents the system calibration results conducted before the satellite integration. Utilizing the data on the performance of the mirror and detectors obtained through the system calibration, combined with simulated data, the ground calibration database can be established. Measuring the relative positions of the mirror and detector system, which were adjusted during system calibration, allows for accurate installation of the entire satellite. Furthermore, the paper outlines the operational workflow of the ground network post-satellite launch.

X-ray follow-up observations of various transients. The first pathfinder of the CATCH mission, CATCH-1, was launched on June 22, 2024, alongside the Space-based multiband astronomical Variable Objects Monitor (SVOM) mission. CATCH-1 is equipped with narrow-field optimized Micro Pore Optics (MPOs) featuring a large effective area and incorporates four Silicon Drift Detectors (SDDs) in its focal plane. This paper presents the system calibration results conducted before the satellite integration. Utilizing the data on the performance of the mirror and detectors obtained through the system calibration, combined with simulated data, the ground calibration database can be established. Measuring the relative positions of the mirror and detector system, which were adjusted during system calibration, allows for accurate installation of the entire satellite. Furthermore, the paper outlines the operational workflow of the ground network post-satellite launch.","manuscriptTitle":"Ground calibration and network of the first CATCH pathfinder","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-09-24 18:17:05","doi":"10.21203/rs.3.rs-4962067/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2024-09-17T00:00:15+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-09-16T17:10:36+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"190984916338917002465986527169536861224","date":"2024-08-28T07:35:26+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-08-28T06:01:12+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-08-27T09:12:34+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-08-26T03:06:48+00:00","index":"","fulltext":""},{"type":"submitted","content":"Experimental Astronomy","date":"2024-08-23T06:49:44+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"experimental-astronomy","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"expa","sideBox":"Learn more about [Experimental Astronomy](http://link.springer.com/journal/10686)","snPcode":"10686","submissionUrl":"https://submission.nature.com/new-submission/10686/3","title":"Experimental Astronomy","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"7a995b9f-fff9-4f43-9206-acdf101a797d","owner":[],"postedDate":"September 24th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2024-11-04T16:23:24+00:00","versionOfRecord":{"articleIdentity":"rs-4962067","link":"https://doi.org/10.1007/s10686-024-09963-7","journal":{"identity":"experimental-astronomy","isVorOnly":false,"title":"Experimental Astronomy"},"publishedOn":"2024-10-31 16:05:08","publishedOnDateReadable":"October 31st, 2024"},"versionCreatedAt":"2024-09-24 18:17:05","video":"","vorDoi":"10.1007/s10686-024-09963-7","vorDoiUrl":"https://doi.org/10.1007/s10686-024-09963-7","workflowStages":[]},"version":"v1","identity":"rs-4962067","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-4962067","identity":"rs-4962067","version":["v1"]},"buildId":"qtupq5eGEP_6zYnWcrvyt","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
